Jean-Pierre Labesse

Jean-Pierre Labesse (born January 4, 1943 ) is a French mathematician who deals with automorphic forms and number theory ( Langlands program ).

Labesse received his doctorate in 1971 under Roger Godement at the University of Paris VII (Denis-Diderot) on the trace formula of Atle Selberg (Thèse d'Etat: La formule des traces de Selberg ) He was for the CNRS in Paris, then professor at the universities of Amiens and Dijon and from 1986 to 2003 he was professor at the University of Paris VII. He was also Directeur des études mathématiques at the École normal supérieure (ENS) and director of the Center International de Rencontres Mathématiques de Luminy (CIRM). He has been a professor in Marseille since 2003 (emeritus since 2008).

Labesse was one of the first to introduce the Langlands program in France. In particular, he dealt with the trace formula of Arthur and Selberg and related to the study of the cohomology of arithmetic groups and the construction of Galois representations of automorphic forms . These techniques were later also central to the proof of the Langlands conjecture for function bodies by Laurent Lafforgue .

He also worked directly with Langlands, for example in a seminar on the trace formula at the Institute for Advanced Study 1983/84 (with Laurent Clozel ).
