Claude Chabauty

Claude Chabauty (born May 4, 1910 in Oran, died June 2, 1990 in Dieulefit) was a French mathematician.

Career

He was admitted in 1929 to the École normale supérieure in Paris.[1] In 1938 he obtained his diploma, majoring in number theory. Consequently he was a professor in Strasbourg.[2] From 1954 on, and for 22 years, he was the director of the department of pure mathematics at the University of Grenoble.[3]

Mathematical work

He worked on Diophantine approximation and geometry of numbers, where he used both classical and p-adic analytic methods.[3] He introduced the Chabauty topology to generalise Mahler's compactness theorem from Euclidean lattices to more general discrete subgroups.[4]
