Laurent Clozel

Laurent Clozel is a French mathematician renowned for his contributions to number theory and the theory of automorphic forms. Born on November 27, 1953, Clozel has been a significant figure in the development of the Langlands program, which seeks to relate Galois groups in algebraic number theory to automorphic representations and harmonic analysis.

Some of his notable work includes:

• Base Change for $\mathrm{GL}(n)$: Clozel has made important contributions to the theory of base change for general linear groups, which is a fundamental aspect of the Langlands program.


• Research on the Ramanujan Conjecture: He has worked on properties of automorphic forms related to the Ramanujan-Petersson conjecture, particularly in higher dimensions.


• Studies on Motives and Galois Representations: Clozel has investigated the connections between motives in algebraic geometry and automorphic forms, contributing to our understanding of how Galois representations arise from automorphic representations.

Throughout his career, Laurent Clozel has held professorial positions at prestigious institutions, such as the University of Paris-Sud (now Paris-Saclay University). He has also collaborated with other leading mathematicians in his field, contributing to significant advancements in modern number theory.
