His work is almost exclusively on calculus, in particular differential equations and functions of a real variable. He generalised Monge's idea of the characteristic of a partial differential equation from 2nd order equations to nth order equations. This work formed a basis of what Lie was to generalise later.
In 1873 he gave a continuous function with divergent Fourier series at any point solving a major problem. The term 'integral equation' is due to Du Bois-Reymond.
