Introduction \endhead %% The purpose of these \GL\/ is to explain to authors the details of electronic manuscript preparation and submission to the AMS and the handling of these papers once they reach the AMS\null. It is assumed that the reader is familiar with \AmSTeX{} and has access to the items listed in the \secref{References} section, especially \JoT\/ \cite{Joy} and {\it \AmSTeX{} Version \rom{2.0} User's Guide} \cite{ATG}\null. Both these \GL\/ and the accompanying examples have been created to help avoid problems before they occur and minimize extra work for all involved in the production of the paper. Instructions for using specific macros will be given in appropriate sections of these \GL. Examples of macro use (input and output) can be found in the sample papers that accompany these \GL. The AMS book series that are published from author-prepared copy may have additional requirements, which are not included here. For specific instructions on preparing an \AmSTeX{} manuscript for such a series, send an inquiry to the address given in the \secref{How to submit a file} section. \subhead Classes of manuscripts covered \endsubhead %% These \GL{} include instructions for preparing both articles and monographs. An article may be intended for either a journal or for a collection such as the proceedings of a conference; where the requirements differ, the differences are explained. A separate section is devoted to monographs, which differ substantially from articles in their requirements. These \GL\/ do not include instructions for preparation of electronic manuscripts for submission to either {\it Abstracts of Papers Presented to the AMS\/} or {\it Mathematical Reviews}. Instructions for {\it Abstracts\/} can be requested from the Society's Publication Division; instructions for {\it Mathematical Reviews\/} can be found on the reverse side of the contents page of any MR issue. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \head 2. General guidelines \endhead %% All manuscripts submitted to the AMS, whether in paper or electronic form, should contain certain information. When that information is missing, extra time and effort are required to obtain it, and this process may result in delays in publication. The following elements should be included with all manuscripts. \roster \item Identification of the series in which the work is to appear. \item Title, including short form if necessary for running head. \item Author name(s), including shortened form if necessary. \item Address(es) of the author(s) where the research was performed, current address(es), and address(es) for electronic mail if available. \item Subject classification(s) (primary and, if appropriate, secondary) according to the {\it Mathematical Reviews\/} Subject Classification. \item Abstract (for a paper to be published in a journal). \endroster Detailed instructions are given later for the form to be used for particular elements, and a checklist is provided to assist authors. Some basic principles are important for effective handling of electronic submissions in production. Authors should keep these in mind when preparing their files. \roster \item Use the \AmSTeX{} preprint format unless you have been provided with a specific alternative for a particular publication. \item \AmSTeX{} contains tags to identify all the important features of mathematical papers and monographs; use them, not tags you define yourself. \item Do not use \TeX{} coding to control line and page breaks. Lines and pages will break differently in the published paper than they did in the file you submit. This is because AMS publications are set in a font (Times Roman) that prints slightly larger and has a different appearance than the font available for general \TeX{} distribution (Computer Modern). If \TeX{} coding were inserted by authors for page and line breaks, it would have to be removed for production. That work could offset any time saved by not having to keyboard the manuscript and errors could be introduced. \item Macro definitions for frequently occurring phrases or mathematical expressions should appear together at the beginning of the file, before the start of the text of the manuscript. Once a macro is created for an expression, it should be used for every occurrence of that expression. \item Do not redefine any plain \TeX{} or \AmSTeX{} control sequences. \item Every file should be able to be processed independently; do not use ``input'' files, but instead include the contents of any such files in the main source file. \item Use \TeX{} coding for special fonts (e.g., boldface or italic) only within the text of the manuscript; do not use such coding for any headings. \item Proofread your manuscript thoroughly and carefully. \endroster %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \head 3. Top matter \endhead %% The top matter associated with a paper includes everything that would appear in a bibliographic reference to the paper, plus additional information about the author(s), subject classifications, keywords, and acknowledgments of support. These elements should be supplied by the author; they will be augmented during production by such things as date received, the publication logo, the copyright notice, and starting page number. These instructions describe only the elements to be provided by the author. \subhead Summary of tags and elements \endsubhead %% The list below includes all the top matter tags associated with the preprint style defined for \AmSTeX{} Version~2.0. This style was designed to be compatible with all AMS journals and collections of papers, and the tags provided are a superset of those required for papers in any of those publications. Requirements for monographs are somewhat different and are described later. The style of the typeset output is controlled by the preprint style. Some of the top matter elements have a ``\ttcs{nofrills}'' option, to permit an author to change the preprint style's default values. For example, the tag \ttcs{keywords} will print the phrase ``{\it Key words and phrases.}''\ just before the key words that are input by the author. The author would use the \ttcs{nofrills} option if he does not want a phrase to precede the key words or if he wants a different phrase. Whether or not a particular tag is required and whether the \ttcs{nofrills} option is available are indicated in the list below. Every file must begin with the statement \ttcs{input amstex}. This must be followed immediately by an appropriate \ttcs{documentstyle} line. The contents of next section, the preamble, are described in more detail following the list of top matter tags. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %% Adjust bad break. \vskip\aboveheadskip \eject %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \settabs\+\kern\exindent &\ttcs{dedicatory...\\enddedicatory}\kern4em % &Required?\quad & \cr \beginexample{} \\input amstex \\documentstyle\{amsppt\} \medskip \ \medskip \+& & & \(Nofrills) \cr \+& & \(Required?) & \(Option?) \cr \+&\\topmatter & \(yes) \cr \+&\\title...\\endtitle & \(yes) & \(yes) \cr \+&\\rightheadtext\{...\} & \(no) & \(no) \cr \+&\\author...\\endauthor & \(yes) & \(no) \cr \+&\\leftheadtext\{...\} & \(no) & \(no) \cr \+&\\affil...\\endaffil & \(no) & \(no) \cr \+&\\address...\\endaddress & \(yes) & \(no) \cr \+&\\curraddr...\\endcurraddr & \(no) & \(no) \cr \+&\\email...\\endemail & \(no) & \(no) \cr \+&\\dedicatory...\\enddedicatory & \(no) & \(no) \cr \+&\\date...\\enddate & \(no) & \(no) \cr \+&\\thanks...\\endthanks & \(no) & \(no) \cr \+&\\translator...\\endtranslator & \(no) & \(no) \cr \+&\\keywords...\\endkeywords & \(no) & \(yes) \cr \+&\\subjclass...\\endsubjclass & \(yes) & \(yes) \cr \+&\\abstract...\\endabstract & \(yes) & \(yes) \cr \+&\\endtopmatter & \(yes) \cr \+&\\document & \(yes) \cr \endexample Note that nearly all the top matter tags are paired, requiring both a beginning and an ending tag. (The few exceptions are associated more with formatting than with content.) If any \ttcs{end...} tag is omitted, an error message will appear at \ttcs{endtopmatter}, if not before. If the forgotten \ttcs{end...} tag is one for which the \ttcs{nofrills} option has been used, the error message will be ``{\tt !~Paragraph ended before \ttcs{next\@} was complete}.'' If the \ttcs{endtopmatter} tag is omitted, none of the top matter material will print. \subhead The preamble\endsubhead %% The area between the \ttcs{documentstyle} line and the \ttcs{topmatter} line is referred to as the ``preamble.'' If any new control sequences are used in the paper, their definitions should be placed in the preamble. Similarly, instructions to access fonts that are not already loaded in \AmSTeX{}, such as bold symbols (see \cite{ATG\rm, pp.\ 14--15}), belong here. By placing these general instructions at the very beginning of a paper, they will be available throughout the entire paper. In addition, this placement will also make it easier for the production staff to find and check them for compatibility when the paper is combined with others to produce the complete publication. When defining new control sequences, always use \ttcs{define}; this will let you know if the name you have chosen has already been used. Do not redefine any plain \TeX{} or \AmSTeX{} command, as this could cause problems in AMS production. New definitions may be used to provide shorthand forms for text or mathematical expressions that are used frequently. They should not include any formatting commands. \subhead Title (required)\endsubhead %% The title should always be entered in the standard AMS style, which is {\bf caps and lowercase}. Major words should begin with capital letters, and lowercase should be used elsewhere. This is true even if the publication in which the paper appears has a style that requires all caps; that form will be generated automatically when the paper is processed at the AMS\null. A multi-line title may be left for \TeX{} to break, or a desired break may be indicated by the author with \ttcs{\\}. Unless the title is very short, the author should provide a form of the title suitable for use in running heads. This should be entered {\bf in all caps} with the tag \ttcs{rightheadtext\{...\}}. \subhead Author information (required)\endsubhead %% The name(s) of the author(s) should be entered in {\bf caps and lowercase} using the tag \ttcs{author}. All caps will be provided automatically if that is the publication style. If the information is more than one line long, a line break may be indicated with \ttcs{\\}. If the author name(s) cannot fit in the space available for the running head, a shortened form should be entered {\bf in all caps} with the tag \ttcs{leftheadtext\{...\}}. Acceptable shortened forms use initials for all but the surname(s), or substitute ``et al.''\ for all names after the first if there are more than two authors. For each author one or more addresses should be input. The address where the research was carried out should be tagged as \ttcs{address ...\\endaddress}. If the current address is different from the research address, the current address should be given next, tagged as \ttcs{curraddr ...\\endcurraddr}. Following these addresses, an address for electronic mail should be given, if one exists, with \ttcs{email ...\\endemail}. Regular, current, and e-mail addresses must be grouped in that order by author; a current address or an e-mail address that is not preceded by an ordinary \ttcs{address} will not print. The tag \ttcs{curraddr} was not defined in the version~2.0 preprint style; it was added in version~2.1. If you are using version~2.0, include the following definition in the preamble of your file to make \ttcs{curraddr} available; this definition will be replaced in production. \beginexample \\def\\curraddr\#1\\endcurraddr\{\\address \ \ \ \{\\it Current address\\/\}: \#1\\endaddress\} \endexample Note that no abbreviations are to be used in addresses, and complete addresses for each author should be entered in the order that names appear on the title page. (Examples are given in the sample article that accompanies these \GL.) Addresses are considered part of the top matter, but in AMS publications they are ordinarily printed at the end of the paper, following the bibliography. Suitable labels will indicate the current and e-mail addresses, typically ``{\it Current address\/}:'' and ``{\it E-mail\/}:'' respectively. The AMS now uses full addresses in all its publications, so \ttcs{affil} is no longer used. \subhead Dedication\endsubhead %% The tag \ttcs{dedicatory} is to be used for such things as ``Dedicated to Professor X on the occasion of his eightieth birthday.'' A dedication will appear in italics, before the abstract. If this is longer than one line, a break may be indicated by \ttcs{\\}. \subhead Acknowledgments of support and other first-page footnotes \endsubhead %% \ttcs{thanks} is used for footnotes that appear on the first page. Unlike \ttcs{address} and \ttcs{email}, \ttcs{thanks} cannot appear more than once in the top matter. It is sometimes desirable, however, to acknowledge support separately for separate authors of a joint paper. Since \ttcs{thanks} creates an unnumbered footnote, separate acknowledgments should be made into separate paragraphs within the footnote. But this brings up a special problem: It's fairly easy to forget the ending~{\tt\}} for a \ttcs{footnote}, so an error-detecting mechanism built into \TeX{} looks for the end of a paragraph within a footnote, and if it sees one, assumes that you've forgotten the~{\tt\}} and issues an error message. In order to end a paragraph without setting off the error-detector, you must use \ttcs{endgraf} instead of a blank line or \ttcs{par}. Papers published in proceedings of conferences are often abstracts or preliminary versions. In such a case, include as a separate paragraph within \ttcs{thanks} the statement ``The final [detailed] version of this paper will be [has been] submitted for publication elsewhere.'' Papers that are to be considered for review by {\it Mathematical Reviews\/} should include the following statement: ``This paper is in final form and no version of it will be submitted for publication elsewhere.'' \subhead Translator\endsubhead %% This element is relevant only to translated papers, and should, if it appears, be the name of the translator. This information will ordinarily be printed at the end of the paper, as ``Translated by'' followed by the translator's name. \subhead Subject information (required)\endsubhead %% Subject classifications and keywords, like acknowledgments, are part of the top matter and will appear as footnotes at the bottom of the first page. Subject classifications are {\bf required}. Subject classifications may be primary (the major topic(s) of the paper) or secondary (subject areas covered by ancillary results, motivation or origin of problems discussed, intended or potential field of application, or other significant aspects worthy of notice). One primary subject classification is required; additional primaries and secondaries are optional. These classifications are entered as \beginexample{} \\subjclass Primary \; \ Secondary \ \\endsubjclass \endexample See the sample article that accompanies these \GL\/ for examples. To determine the classifications, use the 1980 Mathematics Subject Classification (1985 Revision) that appears in annual indexes of {\it Mathematical Reviews\/} beginning in 1984. (The two-digit code from the Contents of MR is {\bf not} sufficient.) Keywords are not required but may be provided by an author if desired. They should be tagged as \ttcs{keywords ...\\endkeywords}. \subhead Abstract (required)\endsubhead %% The abstract is input with \ttcs{abstract...\\endabstract}. It may comprise multiple paragraphs and include displayed material if appropriate. The length of the abstract depends primarily on the length of the paper itself and on the difficulty of summarizing the material, but an upper limit of about 150 words for short papers and 300 words for long papers is suggested. Though the styles of various publications may differ somewhat, the preprint style is typical. The abstract will be set in eight point type on a narrower measure than the body of the paper, centered on the first page, with the label ``{\smc Abstract.}''\ provided automatically as the first word of the first paragraph. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \head 4. Document body \endhead %% There are two essentially different types of documents that may appear in AMS publications, individual papers (in journals or collections of proceedings) and monographs. This section contains descriptions of those elements that are common to both types of documents. \subhead Headings\endsubhead %% Four levels of headings are provided to permit logical sectioning of a manuscript. These headings are applicable to papers and within chapters of a monograph. \beginexample{} \\specialhead...\\endspecialhead \\head...\\endhead \\subhead...\\endsubhead \\subsubhead...\\endsubsubhead \endexample \ttcs{specialhead} is for long articles that need extra divisions (e.g., chapters, parts) at a level above the \ttcs{head} level. In the preprint style \ttcs{specialhead} uses boldface type and is set flush to the left margin on a line by itself. \ttcs{head} is small caps, centered; \ttcs{subhead} is boldface, flush to the left margin, and run in with the following text; and \ttcs{subsubhead} is italic, indented as for an ordinary paragraph, and run into the text. The style shown in these \GL\/ is that of the preprint style, which is based on the style of the \JAMS; \ttcs{head} is the highest level used in this document. Explicit line breaks are obtained by \ttcs{\\} in a \ttcs{head} or a \ttcs{specialhead}, but for \ttcs{subhead} and \ttcs{subsubhead}, which are part of their paragraph, just use \ttcs{linebreak} as you would in normal paragraphed text. Do not leave a blank line after any heading. If you prefer the appearance of a blank line (so that the file is easier to read), a comment line (containing only a {\tt\%}) is a good substitute. If you are preparing a monograph, there are some additional considerations relevant to headings. For details, see the \secref{Monograph formatting} section. \subhead Mathematical text\endsubhead %% For instructions on preparing mathematical text, the author is referred to \JoT\/ \cite{Joy} and the sample article which accompanies these \GL. Care should be taken to use math mode for {\it all\/} mathematical expressions, no matter how short or insignificant. For example, in the phrase ``a group of class 2,'' the ``2'' should be treated as mathematical text and placed between dollar signs: {\tt \$2\$}. One reason for this is that numerals are always roman in mathematical expressions, whereas in ordinary text environments \TeX{} sets them in the style of the surrounding text; see also the \secref{Roman type} section below. The sample paper that accompanies these \GL\/ contains some mathematical examples, intended to illustrate the recommended manner of input. The input file for the sample paper should be examined to clarify the details of input conventions. \subhead Lists\endsubhead %% Lists are produced by \ttcs{roster...\\endroster}, with the individual items tagged by \ttcs{item}. Most details of input are given in \JoT\/ \cite{Joy\rm, Chapter 19, \bf Roster}. In addition to what is described there, the amount of indentation can be adjusted to accommodate wide item numbers. Just before beginning the \ttcs{roster}, type, for example, \ttcs{widestnumber\\item\{(viii)\}}. This adjustment is temporary; the default will be reinstated by \ttcs{endroster}. For an example of the use of \ttcs{roster}, see the Lemma in the sample paper. \subhead Theorems, lemmas, and other proclamations\endsubhead %% There are several varieties of proclamations and related objects. All have the same generic form: \beginexample{} \\\\{\\} \ \ \\end\ \endexample \noindent The following list gives the specific tags recognized by the preprint style, along with the types of heading text for which each is to be used. \beginexample{\exboxwidth=1.85in} \exbox{}{\\proclaim ...} Theorem, Lemma, Corollary, Proposition, \exbox{}{\ \ \ \ \\endproclaim} Criterion, Algorithm, Condition \exbox{}{\\demo ... \\enddemo} Proof \exbox{}{\\remark ...} Remark, Note, Notation, Claim, Summary, \exbox{}{\ \ \ \ \\endremark} Acknowledgment, Case, Conclusion \exbox{}{\\definition ... \\enddefinition}\newline % Definition, Conjecture, Problem \exbox{}{\\example ... \\endexample} Example \endexample Note that all these objects should have both their beginnings and ends marked in the file. The \ttcs{proclaim} text will be set in ``slanted'' type by the preprint style. The text for all other classes of proclamations will be roman. ({\sl Slanted type is essentially the same as roman, but the letters are slightly skewed;} {\it letters in italic type are drawn in a different style.}) In the absence of a matching \ttcs{endproclaim}, slanted type would continue beyond where it should; for this reason, the tags for all other classes of proclamations include a check for a ``runaway'' \ttcs{proclaim} and will report it if one is detected. Punctuation and spacing are provided automatically for the heading text. If something different is required, \ttcs{nofrills} can be used with any of these tags. \subhead Roman type\endsubhead %% Numbers, punctuation, (parentheses), [brackets], \{braces\}, and symbols used as labels should always be set in roman type. This is true even within the statement of a theorem, which is set in slanted type by the preprint style. Be careful to distinguish between roman elements that are mathematical in nature (e.g., ``a group of class 2''), and those that are part of the text (e.g., a label or a year). Mathematical expressions are, as usual, enclosed within dollar signs {\tt \$...\$}; roman text elements should be coded as \ttcs{rom\{...\}} in non-roman environments such as theorems. The version 2.0 preprint style did not include a definition of \ttcs{rom}; it was added in version 2.1. if you are using version~2.0, insert this definition into the preamble of your file to make \ttcs{rom} available. \beginexample{} \\define\\rom\#1\{\{\\rm \#1\}\} \endexample Abbreviated forms of mathematical terms are also usually set in roman type, to distinguish them from mathematical variables or constants. Use the control sequences for common mathematical functions and operators like $\log$ and $\lim$ (see \cite{Joy\rm, Chapter 14}). The style of reference citations is publication dependent. In order to ensure consistency, always use \ttcs{cite} when citing a reference. Although the reference indentifier is roman in the preprint style, it may be set automatically in bold in some publications, so you will need to set any additional information in roman type as illustrated by the coding of the citation in the previous paragraph: \beginexample{} \\cite\{Joy\\rm, Chapter 14\} \endexample \subhead Figures, tables, and other inserts with captions\endsubhead %% Figures, tables, and some other kinds of objects are usually handled as inserts. These objects may be prepared separately from the main document and pasted in, in which case space must be left for them. Sometimes, however, a table or certain kind of figure (e.g.\ a commutative diagram) can be prepared with \TeX, but it may be so large that fitting it in at the point of reference may cause problems with paging. In either case, the object should be specified as a floating insert, which can be repositioned automatically as required for good pagination. AMS guidelines provide that such an object should follow as closely as possible its first reference in text, if possible on the same page where it is mentioned. When this is not possible, a reference will be added, ``(See Figure $n$, page $m$.).'' An author should use the control sequence \ttcs{topinsert}, which specifies that an insert is to go at the top of a page. If an insert does not fit on the page where specified, \TeX{} will automatically shift it to the top of the next page. The final placement of inserts will be determined by the AMS editorial staff, on the basis of the most appropriate page layout. These floating objects usually have captions; a caption is usually positioned above a table and below a figure. This is the general structure used to specify a figure insert, with a caption at the bottom. \beginexample{} \\topinsert \ttcs{vspace}\{\Dimen\}\quad{\rm or}\quad% \ \ttcs{captionwidth}\{\Dimen\}\quad{\rm(optional)} \\botcaption\{\\} \ \ \\endcaption \\endinsert \endexample The general structure for a table insert, with a caption at the top, is the following. \beginexample{} \\topinsert \ttcs{captionwidth}\{\Dimen\}\quad{\rm(optional)} \\topcaption\{\\} \ \ \\endcaption \ttcs{vspace}\{\Dimen\}\quad{\rm or}\quad% \ \\endinsert \endexample The \ttcs{vspace\{\Dimen\}} option should be used to leave blank space for an object to be pasted into place. If a \Dimen{} is specified, its value should be the exact height of the object to be pasted in. Extra space around the object and the caption are dependent on the document style and will be provided automatically. The \ttcs{captionwidth\{\Dimen\}} option may be used to override the default caption width specified by the document style. For the preprint style, the default caption width is 4pc narrower than the page width (30pc). In the preprint style, a figure (bottom) caption narrower than the caption width will be centered on the text width of the page. The \ is something like ``Figure~1'' or ``Table~2a''. Do not type any final punctuation; it will be provided. The caption label will be set in caps and small caps. The \ is any descriptive text that may be desired. The preprint style will set this in roman. Even if there is no text, the \ttcs{endcaption} tag must be present. If you choose to include the \TeX{} code for a figure, table, or other captioned object in the input, then omit the \ttcs{vspace\{\Dimen\}} line and type the code in the area indicated. The size will be calculated automatically and the caption set in the appropriate location above or below the object. Separate art work should be drawn in black ink with clean, unbroken lines on nonabsorbent paper. Labels should match those used in the text. Authors' originals are used whenever possible in AMS journals; for articles in a book series, art may be redrawn for consistency of style throughout a volume. The originals of photographs or computer-generated images should be sent to the AMS as part of the art package. For a color image (whether it will be converted to a black and white image or appear in color), the color negative or transparency is needed. To avoid damage to photographic images, do not use paper clips or staples, and do not tape them to a sheet of paper. A photocopy of such an image can be used to identify it. There are no special macros to support the creation of tables in \AmSTeX{}. Table macro packages, which are available from other sources, can be used, but tables prepared in this way should be placed in a separate file and processed separately. {\tt.dvi} files for separately processed tables can be sent to the AMS on diskette for output on the typesetter; this is encouraged, as it will ensure output of high quality equivalent to that of the article or monograph. ({\tt.dvi} files, like other binary files, cannot be sent via ordinary electronic mail.) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \head 5. Bibliographic references \endhead %% The references section of a paper begins with \ttcs{Refs} and ends with \ttcs{endRefs}. \ttcs{Refs} sets the head for the references, switches to eight-point type and makes a few other changes behind the scenes, and \ttcs{endRefs} restores the body style. This is convenient in documents where small bibliography listings are scattered throughout, as in some survey papers. In a monograph, where the bibliograpy forms a separate chapter, the chapter title should be entered in the manner described in the \secref{Monograph formatting} section below. After the top matter, the line \ttcs{Refs\\nofrills\{\}} should be entered to set up the proper references format. Items in the bibliography are usually ordered alphabetically by author. They may be numbered consecutively or labeled with some other ``key.'' These references are set with hanging indentation. The amount of indentation is preset to accommodate the most common case of reference labels, two-digit numbers. It can be increased (or decreased) by specifying the widest number or key used in the references. For example, \beginexample{} \\widestnumber\\no\{999\} \\widestnumber\\key\{GHMaR\} \endexample \noindent will increase the indentation to accommodate a three-digit number or the key \hbox{[GHMaR]} respectively. (Only one style of reference labels should be used in a manuscript, of course.) Note that the parts of the formatting that depend on the current publication style are taken into account automatically (the period after a number or the [\dots]\ around a key, plus the usual space). You can also specify \ttcs{widestnumber\\no\{9\}} to reduce the indentation from two digits' worth to one, if your bibliography has fewer than ten entries. The elements of a bibliographic reference should be given in the order and with the tags listed below. Those that are required are so marked. Examples are given in the two sample papers that accompany these \GL\/; relevant references are cited with most tags by labels in [brackets]. \subhead All references\endsubhead %% Several tags must be present for all reference items. The beginning and end of each item must be indicated explicitly. Otherwise, only the beginning of a new element is marked by the presence of a tag. Final punctuation should always be omitted, except where noted explicitly. \ttcs{ref} \req{} is used to indicate the beginning of a reference; the end of each reference must be indicated by \ttcs{endref}. \ttcs{no} or \ttcs{key} \req{} is used to specify the reference number or label by which citations to the reference are referred in the text of the paper. (Numbered references are used in the sample article, and references with keys in the sample monograph chapter that accompany these \GL.) \ttcs{nofrills} may precede a tag to suppress the final punctuation on the preceding element (see \cite{15} in sample article); it may also follow a tag to suppress the punctuation at the end of the data identified by that tag (see \cite{23} in sample article). \subhead Journal articles\endsubhead %% {}\endgraf % no text with this heading, intentionally \ttcs{by} \req{} indicates the beginning of the author name(s) (see \cite{4}, \cite{8}, et al.\ in sample article). Give at least one full name; initials and last name is an acceptable form. If a subsequent reference is by the same author(s), use \ttcs{bysame} instead, with no data following it (see \cite{8}). \ttcs{paper} \req{} marks the beginning of the title (see \cite{4}, \cite{5}, et al.\ in sample article). In a title the first word and any proper names should begin with capital letters; everything else should be lowercase. (In a German title, all nouns should begin with capital letters (see \cite{11}).) If a title is followed by a part number, the title proper should be terminated by a period, and the part number coded as \ttcs{rom\{...\}} (see \cite{11}, \cite{15}). \ttcs{paperinfo} is used to tag additional information about the title of an article, such as an addendum (see \cite{17} in sample article) or part number (see \cite{22}). \ttcs{jour} \req{} begins the name of the journal, in abbreviated form (see \cite{4}, \cite{8}, et al.\ in sample article). Refer to {\it Abbreviations of Names of Serials Reviewed in Mathematical Reviews\/} \cite{ASMR}, to annual indexes of {\it Mathematical Reviews\/}, or to the American Standard for Periodical Title Abbreviations (National Clearing House for Periodical Title Word Abbreviations, Columbus, Ohio, 1969) for standard journal abbreviations. If the journal name is modified by a series name, include that information following the name, in parentheses (see \cite{24}). \ttcs{vol} is used to tag the volume number (see \cite{5}, \cite{17}, et al.\ in sample article). \ttcs{issue} is used to tag the issue number (see \cite{17} in sample article); this should be omitted except where to do so would result in an ambiguous reference. \ttcs{yr} \req{} tags the year of publication. If the paper has not yet appeared in print, \ttcs{toappear} should replace the year (see \cite{7} in sample article). For some journals, the volume number is the same as the year of publication (see \cite{17}); in such a case, \ttcs{vol} should be used, not \ttcs{yr}. \ttcs{pages} should be followed by the span of pages covered (see \cite{4}, et al.\ in sample article). Use \ttcs{page} if the reference is only one page in length (see \cite{17}). \ttcs{lang} is used to tag language information (see \cite{17}, \cite{24} in sample article). This is used most often to identify Russian articles when their titles have been translated. \ttcs{finalinfo} may be used to include additional relevant information, e.g.\ ``(overview)'' (see \cite{15} in sample article); note the use of \ttcs{nofrills} in this example. \subhead Books\endsubhead %% This form of reference should be used only for complete books. This will ordinarily be either a monograph or a reference to an entire collection, but it may also be used for dissertations, reports, and similar documents. \ttcs{by} or \ttcs{bysame} \req{} are used in the same way as for a journal article (see \cite{1}, \cite{2} in sample article). If the reference is to an edited collection, such as the proceedings of a conference, insert ``(ed.)''\ or ``(eds.)''\ following the name(s) as appropriate (see \cite{9}, \cite{13}). \ttcs{book} \req{} tags the title of the book (see \cite{1}, \cite{8} in sample article). Dissertations are best treated as books (see \cite{7}). Collections referred to as a whole should also be entered as books (see \cite{9}, \cite{13}). Part numbers should be treated the same as for papers, using \ttcs{rom\{...\}} (see \cite{1}, \cite{2}). \ttcs{bookinfo} is used to tag book information in addition to the title, such as edition (see \cite{3} in sample article), identification of the reference as a dissertation (see \cite{7}), identification of a conference and its location in the case of a proceedings volume (see \cite{9}), etc. \ttcs{publ} \req{} tags the name of the publisher; use abbreviated form (see \cite{1}, \cite{6}, et al.\ in sample article). \ttcs{publaddr} \req{} is followed by the name of the city and state or the foreign city where the book was published (see \cite{3}, \cite{10}, et al.\ in sample article). \ttcs{yr} \req{} is the same as for a journal article (see \cite{1}, \cite{3}, et al.\ in sample article). \ttcs{lang} is the same as for a journal article (see \cite{1} in sample article). \ttcs{finalinfo} is the same as for a journal article. \subhead Articles in books\endsubhead %% These references contain elements common to both journal articles and book references. \ttcs{by} or \ttcs{bysame} \req{} are used in the same way as for a journal article (see \cite{10}, \cite{19} in sample article). \ttcs{paper} \req{} likewise is similar to a journal article (see \cite{10}, \cite{18} in sample article). \ttcs{inbook} \req{} is followed by the title of the book (see \cite{10}, \cite{16} in sample article). In this title, all important words begin with capital letters. If the book is the proceedings of a conference, the location and date of the conference should follow the title in parentheses (see \cite{16}). \ttcs{ed} or \ttcs{eds} \req{} is followed by the name of the editor or editors, respectively (see \cite{21} in sample article). \ttcs{bookinfo} is similar to a book reference (see \cite{6} in sample article). (Note also the use of \ttcs{nofrills} in this reference.) \ttcs{vol} is used to tag volume information for a book series. Only the volume number should be input; ``vol.''\ will be provided (see \cite{10} in sample article). \ttcs{publ} and \ttcs{publaddr} \req{} are used in the same way as for books (see \cite{10}, \cite{16}, \cite{19} in sample article). \ttcs{yr} \req{} is the same as for a journal article (see \cite{10}, et al.\ in sample article), as is \ttcs{toappear} (see \cite{19}). \ttcs{page} or \ttcs{pages} is the same as for a journal article (see \cite{10}, et al.\ in sample article). \ttcs{lang} is the same as for a journal article. \ttcs{finalinfo} is the same as for a journal article. \subhead Extended references\endsubhead %% Sometimes several references are listed together, for example, parts of a long paper that have been published separately. Another type of reference that can list multiple sources is a work cited both in the original and in translation. In either case, after the first reference is complete, one of the tags below indicates the beginning of an additional reference; this subsequent reference should be coded with all the tags appropriate to the type of reference in the same order as for a first reference. \ttcs{moreref} is used to indicate the beginning of an additional full reference; it takes no data, but is followed by the tags and data appropriate to the type of reference (see \cite{15}, \cite{17} in sample article). \ttcs{transl} is followed by the information that describes a translation (see \cite{1}, \cite{2}, \cite{23} in sample article). The tags and data for the translated work follow in the same order as for an ordinary reference. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \head 6. Monograph formatting \endhead %% A monograph will usually consist of multiple chapters. Several features are available in the preprint style that will set your output as a chapter rather than as an individual paper. For example, the positioning of the title on the first page is different; also the text of a \ttcs{head} in a monograph will be boldface instead of caps and small caps; headings of theorems, propositions, definitions, remarks, etc., will be caps and small caps instead of boldface, and indented rather than flush left. For most AMS book series, authors can obtain style files with instructions for the particular book from the Publications Department. (Write to the address given in the \secref{How to submit a file} section.) Using the preprint style, each chapter must be prepared as a separate document in a separate file. These files should be given meaningful names, so that when they are transmitted to the AMS, there will be no question about which file represents which chapter. Information that identifies the author(s), the subject matter of the monograph, acknowledgments of support, and so forth, will appear in the front matter of the book. Place this information in a file called \filnam{bookinfo.fil} and use the tags associated with the top matter of an article. (See the \secref{Top matter} section.) In each chapter file, you must signal your intentions by typing \ttcs{Monograph} in the preamble, right after the \ttcs{documentstyle} line. A typical monograph chapter would begin like this: \beginexample{} \\input amstex \\documentstyle\{amsppt\} \\Monograph \\topmatter \\title\\chapter\{4\} Matrix Algebras\\endtitle \\endtopmatter \endexample \subhead Chapter titles\endsubhead %% There are three common variations of the chapter title, of which the form shown above with a chapter number is most common. Here the number that follows \ttcs{chapter} is converted automatically to roman numerals and the word ``{\eightpoint CHAPTER}'' is added. (The second sample paper that accompanies these \GL\/ illustrates the format of such a monograph chapter.) The second variation is a chapter title in which some other heading, such as ``Appendix,'' replaces the word ``Chapter.'' In such cases \ttcs{nofrills} is used: \beginexample{} \\topmatter \\title\\chapter\\nofrills\{APPENDIX B\} Poisson Integral\\endtitle \\endtopmatter \endexample \noindent The replacement text given with \ttcs{chapter} will appear exactly as typed. The third variation is used for an element such as a preface or introduction, which has no pretitle text at all. For this, omit the \ttcs{chapter} command: \beginexample{} \\topmatter \\title Preface\\endtitle \\endtopmatter \endexample \subhead Table of contents\endsubhead %% In monographs, the table of contents should be a separate chapter. Start by typing the title ``Contents'' as for a preface or introduction, and then use the \ttcs{toc...\\endtoc} structure as the body of the document (rather than putting it in the top matter, as you would for a journal article). \beginexample{} \\topmatter \\title Contents\\endtitle \\endtopmatter \bigskip \\document \\toc \\title Preface\\page\{vii\}\\endtitle \\title\\chapter\{1\} Matrix Algebras\\page\{1\}\\endtitle \\head\{\} Continuous complex-valued functions\\page\{1\}\\endhead \\subhead\{\} Examples\\page\{4\}\\endsubhead ... \\title Appendix B. Poisson Integral \\page\{297\}\\endtitle \\title Bibliography\\page\{307\}\\endtitle \\endtoc \\enddocument \endexample For the table of contents chapter titles are typed in a form similar, but not identical, to that used for the title at the beginning of a chapter. In particular, the second variation (the one for which \ttcs{nofrills} was used) is typed without a \ttcs{chapter} tag; instead, put a period after the text that appeared as an argument to \ttcs{chapter}. The other two variations are typed the same way for both chapter titles and tables of contents. To put page numbers in the table of contents, use \ttcs{page} as shown, just before the ending of an element. This option is available for all levels of headings. If a \ttcs{head}, \ttcs{subhead}, or \ttcs{subsubhead} entry does not have a section number, it is necessary to follow that tag with an empty group ({\tt \{\}}) followed by a space. The contents macros look for the space in order to align the section titles properly. \subhead Monograph running heads\endsubhead %% In a monograph prepared using the preprint style, the chapter title is used for the left running head and the text of section headings (from \ttcs{head}) appears as the right running head. It is not uncommon for the text of a heading to be too long to fit in the running head width; in such a case use \ttcs{rightheadtext} to specify a shortened form of the heading for use in the running heads: \beginexample{} \\head Fourier coefficients of continuous periodic functions of bounded entropy norm\\endhead \\rightheadtext\{Fourier coefficients of periodic functions\} \endexample \noindent This should follow immediately after the \ttcs{head}, to ensure that both take effect on the same page. If the chapter title is too long to fit as a running head, a shortened form can be supplied in a similar way with \ttcs{leftheadtext} immediately after the \ttcs{title}. See also the \secref{Running Heads} section. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \head 7. How to submit a file \endhead %% First send two proof copies of the manuscript to the appropriate journal or book series editor. You should state your intention to submit the manuscript electronically, but the electronic version should not accompany the proof copy. Upon acceptance of the paper, the source file should be sent to the Providence office. Before sending the source file, be sure to proofread your article or monograph carefully, as if you were preparing it for publication yourself---you are! The files that you send must be the ones used to prepare the proof copy that was accepted for publication. The source file may be submitted either by electronic mail or on diskette. Whichever method is used, a few simple guidelines apply. \roster \item An \AmSTeX{} manuscript should be prepared using the ``preprint style'' according to the guidelines given above, plus whatever additional guidelines may have been given in instructions for a particular journal or book series. \item Two printed copies of the manuscript, including art, should be sent to \beginexample{\advance\exindent by\rosteritemwd \rm} Publications Department \AMS 201 Charles St. P. O. Box 6248 Providence, RI 02940-6248 \endexample \noindent The printed manuscript should indicate that the article was prepared and submitted electronically. (The notice ``Typeset by \AmSTeX{}'' inserted by the preprint style is sufficient.) \item The files should be complete, including your personal macro set if one was used. (If the manuscript is a single paper, personal macros should be installed in the preamble, so that only one file is needed.) The files should be the same versions used to prepare the printed copy. \item Only necessary files should be sent. Do not include {\tt.dvi} or transcript files; one of the first steps in processing is to \TeX{} the files you have sent using the AMS production headers. \item Use meaningful file names, and include the file name in a comment at the top of the file. (See the sample paper input for an example.) \item A covering letter (electronic, if the files are sent by electronic mail) should identify the author(s) and title of the paper, the publication in which it is to appear, and include a list of the files being sent, stating the significance of each. If there is only one file and it is being sent by electronic mail, the file should be appended to the letter and both sent in a single message. \endroster \noindent Only files for articles that have been accepted for publication will be processed. Files for which no approval has been transmitted by the journal or book series editor will be held until approval is received. \subhead Submitting files by electronic mail\endsubhead %% Files sent by electronic mail should be addressed to the Internet address \beginexample{\rm} pub-submit\@Math.AMS.com \endexample If the manuscript comprises more than one file, each file (or part of a file) should be sent in a separate message. The subject line of the message should identify the file by name; if one file has been broken into parts on account of its large size, also identify the part---``part $n$ of $m$''---in the subject line. Files received by electronic mail will be acknowledged within five business days. If you do not receive an acknowledgment within that time, please inquire; see the \secref{Getting help} section below. \subhead Submitting files on diskette\endsubhead %% Files may be sent on diskettes in any standard format and density appropriate for either IBM PC-compatible or Macintosh. Label diskettes with your name, the title of your paper, and the publication for which it is intended. Diskettes and covering letters should be sent to the Publications Department at the address shown above. As diskettes are reusable, please make sure that all irrelevant files that may remain from other work have been deleted. Time spent by the production staff in trying to identify extra files will delay processing of your paper. A package containing a diskette should be clearly marked ``Floppy disk. Do not fold or bend. Do not expose to electric motors or other magnetic fields.'' Mailers designed for diskette shipment are available from many sources; if you do not use a special mailer, cardboard or some other stiffener should be enclosed in the package for protection. Files received on diskette will be acknowledged as soon as possible after they are received. If you have not received an acknowledgment within a reasonable amount of time (two weeks if you are located in the North America, three weeks if in Europe, Australia, Japan, or South America, a month if you are in Eastern Europe or Asia), please inquire, writing to the same address to which you sent the diskette. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \head 8. What happens to a file once it reaches the AMS \endhead %% When an electronic manuscript is received, the files are logged in for tracking through the production process and matched with the paper copy of the manuscript if that was sent separately. Once it has been determined that everything has been received, the files are sent to the Composition Department for preliminary processing. At this stage, only those steps are taken that are necessary to ensure that the files will run successfully with the production headers. These steps include the following. \roster \item Make additions or changes necessary to conform to the requirements of the production headers; this may include adding journal volume and issue numbers, for example. \item Scan the preamble and remove any definitions that conflict with definitions in the production headers. \item Remove hard-coded spacing that is intended only for formatting; this includes \ttcs{vskip}, \ttcs{bigskip}, control spaces, and the like. Some spacing commands will be retained, in particular those that leave space for insertion of figures or tables or those included for the sense of mathematical expressions, for example the thinspace in $dx\,dy$ ({\tt\$dx\\,dy\$}). \item Run the files through \AmSTeX{} using the production headers. Make adjustments as necessary until this \AmSTeX{} run is error-free. \endroster The AMS production headers will be different in several respects from the headers used by the author. \roster \item Times Roman fonts will be used, rather than the Computer Modern used for the preprint and other styles distributed to authors. \item Page dimensions may be changed, depending on the publication. The style and formatting of the top matter may also differ. \item The publication logo and copyright notice will be present, and the notice ``Typeset by \AmSTeX{}'' will be removed. \endroster The output of this \AmSTeX{} run is delivered to the Editorial Department, % where it is assigned to a production editor. This proof is marked to note changes that must be made so that it will conform to the style of the journal or book series. The proof is returned to the Composition Department, where the marked corrections are made in the files. It is usually this stage that is most sensitive to inconsistencies in the input coding. For example, assume that a control sequence has been defined to replace a frequently used expression, but some instances of that expression in the text are spelled out rather than input with the control sequence. If the expression needs to be changed corrections are marked on occurrences of the expression in the proof text. When making corrections the keyboarder will find the corresponding control sequence in the file text and will change the definition, but will then assume that the definition has been used throughout and will not look for exceptions. It is for this reason you must use the control sequence for every occurrence of the expression. After corrections, the file is rerun through \AmSTeX{}, and the output returned to the Editorial Department. The corrections are checked, and anything that does not conform to the previous markings is marked again. This marked proof is then returned to the author for approval. Any minor changes or corrections the author wishes to make after receiving the marked proof should be submitted on paper. Extensive revision is not allowed at this stage. Changes will be copymarked and keyed by the Providence staff as for a non-electronic manuscript. Electronic corrections or completely new submissions are not accepted. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \head 9. Checklist \endhead %% Please use the following list in your final check as you package your files to be sent to the AMS. \roster \item Top matter is complete. Title, author(s), address(es), including current and e-mail addresses, subject classification(s), and (for a journal paper except in the \JAMS\/) abstract are required. If appropriate, the \ttcs{thanks} footnote states whether the manuscript is preliminary or in final form. For a monograph, the overall ``top matter'' is included in a separate file \filnam{bookinfo.fil}. \item Author-defined macros have been used throughout, for every occurrence of the strings or expressions that they define. \item All author-defined macros are isolated in the preamble; for a multi-chapter monograph, the same macros should be included in the preamble of every file. \item No \TeX{} commands have been used that are intended for formatting; you have used only the tags provided in the preprint style. \item You have proofread the manuscript carefully and thoroughly. \item All files referred to in the job are included, and they have meaningful names. %% No nested roster support in AMS-TeX; use PLAIN techniques. {% \itemitem{(a)} If files are being sent on diskette, no unnecessary files are present. \itemitem{(b)} If files are being sent by electronic mail, only one file is sent for an article, and an explanatory message has been included at the top of the file. For a monograph comprising multiple files, each file is sent in a separate message with a subject line that identifies it clearly. If any large file must be broken into pieces, the subject line also identifies which part of how many. \par} \item The files that are being sent are the same ones that produced the proof output. \item A covering letter or explanatory message identifies the author(s), title, intended publication (journal or series), and list of files. \item The covering letter or explanatory message also tells how you can be reached throughout the publication process. Be sure to notify us if your address changes during this period. \endroster %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \head 10.
