Jean L. Mawhin (born 11 December 1942 in Verviers) is a Belgian mathematician and historian of mathematics.
Mawhin received his PhD in 1969 (Le problème des solutions périodiques en mécanique non linéaire)[1] under Paul Ledoux at the University of Liège, where he had studied since 1962 and received his licentiate in mathematics in 1964.
He was assistant professor at Liège from 1964 and maitre de conferences (lecturer) from 1969 to 1973.
He worked on (nonlinear) ordinary differential equations and the topological methods used there (fixed-point theorems, Leray-Schauder theory) and methods of nonlinear functional analysis.
