Jean-Michel Bony

Jean-Michel Bony (born 1 February 1942 in Paris) is a French mathematician, specializing in mathematical analysis.

Bony completed his undergraduate and graduate studies at the École Normale Supérieure, where he received his Ph.D in 1972 with thesis advisor Gustave Choquet. Bony became a professor at the University of Paris-Sud and is now a professor at the École Polytechnique.

His research deals with microlocal analysis, partial differential equations and potential theory. In 1981 he published important results on paradifferential operators, extending the theory of pseudifferential operators published by Ronald Coifman and Yves Meyer in 1979. Bony applied his theory to the propagation of singularities in solutions of semilinear wave equations.

He was elected in 1990 a corresponding member and in 2000 a full member of the French Academy of Sciences.

He was an Invited Speaker at the ICM in 1970 in Nice and in 1983 in Warsaw.
