Michel Duflo (born 15 August 1943) is a French mathematician who works in the representation theory of Lie groups.
From 1962, Duflo studied at the École normale supérieure and received a doctorate under the supervision of Jacques Dixmier. Currently, he is an emeritus professor at the University of Paris VII (Denis Diderot) at the Institut de Mathématiques de Jussieu, and at the École normale supérieure.
Duflo has worked on the orbit method of Alexander Kirillov. He introduced the Duflo isomorphism, an isomorphism between the center of the enveloping algebra of a finite-dimensional Lie algebra and the invariants of its symmetric algebra.
In 1974 he was an invited speaker at the International Congress of Mathematicians in Vancouver (Inversion formula and invariant differential operators on solvable Lie groups). Duflo received the Prix Le Conte of the French Academy of Sciences; in 1986 he became a corresponding member of the Academy.
His students include Laurent Clozel.
His daughter is the Nobel prize-winning economist Esther Duflo.
Jean-Pierre Serre is a French mathematician who has made contributions to algebraic topology, algebraic geometry, and algebraic number theory. He was awarded the Fields Medal in 1954, the Wolf Prize in 2000 and the inaugural Abel Prize in 2003.
Jean Leray was a French mathematician, who worked on both partial differential equations and algebraic topology.
Élie Joseph Cartan was an influential French mathematician who did fundamental work in the theory of Lie groups, differential systems, and differential geometry. He also made significant contributions to general relativity and indirectly to quantum mechanics. He is widely regarded as one of the greatest mathematicians of the twentieth century.
Anatoly Ivanovich Maltsev was born in Misheronsky, near Moscow, and died in Novosibirsk, USSR. He was a mathematician noted for his work on the decidability of various algebraic groups. Malcev algebras, as well as Malcev Lie algebras are named after him.
Michel Raynaud was a French mathematician working in algebraic geometry and a professor at Paris-Sud 11 University.
Patrick Dehornoy was a mathematician at the University of Caen Normandy who worked on set theory and group theory.
Luc Illusie is a French mathematician, specializing in algebraic geometry. His most important work concerns the theory of the cotangent complex and deformations, crystalline cohomology and the De Rham–Witt complex, and logarithmic geometry. In 2012, he was awarded the Émile Picard Medal of the French Academy of Sciences.
Jean-Loup Waldspurger is a French mathematician working on the Langlands program and related areas. He proved Waldspurger's theorem, the Waldspurger formula, and the local Gan–Gross–Prasad conjecture for orthogonal groups. He played a role in the proof of the fundamental lemma, reducing the conjecture to a version for Lie algebras. This formulation was ultimately proven by Ngô Bảo Châu.
Michel Demazure is a French mathematician. He made contributions in the fields of abstract algebra, algebraic geometry, and computer vision, and participated in the Nicolas Bourbaki collective. He has also been president of the French Mathematical Society and directed two French science museums.
In mathematics, the Duflo isomorphism is an isomorphism between the center of the universal enveloping algebra of a finite-dimensional Lie algebra and the invariants of its symmetric algebra. It was introduced by Michel Duflo (1977) and later generalized to arbitrary finite-dimensional Lie algebras by Kontsevich.
Claudio Procesi is an Italian mathematician, known for works in algebra and representation theory.
Corrado de Concini is an Italian mathematician and professor at the Sapienza University of Rome. He studies algebraic geometry, quantum groups, invariant theory, and mathematical physics.
Michèle Vergne (born August 29, 1943, in L’Isle-Adam, Val d´Oise) is a French mathematician, specializing in analysis and representation theory.
Thomas Jones Enright was an American mathematician known for his work in the algebraic theory of representations of real reductive Lie groups.
Jean-Michel Bony is a French mathematician, specializing in mathematical analysis. He is known for his work on microlocal analysis and pseudodifferential operators.
Zoé Maria Chatzidakis is a mathematician who works as a director of research at the École Normale Supérieure in Paris, France. Her research concerns model theory and difference algebra. She was invited to give the Tarski Lectures in 2020, though the lectures were postponed due to the COVID-19 pandemic.
Laurent Clozel is a French mathematician. His mathematical work is in the area of automorphic forms, including major advances on the Langlands programme
