Jacques Tits

Jacques Tits is a Belgian mathematician, born in 1930. He has written and cowritten a large number of papers on a number of subjects, principally algebra.

He introduced the theory of buildings, which are combinatorial structures on which groups act, in many cases of interest in algebraic group theory (including finite groups, and groups defined over the p-adic numbers).

Tits received the Cantor Medal from the Deutsche Mathematiker-Vereinigung (German Mathematical Society) in 1996.
