Pierre Collet (born 1948) is a French mathematical physicist, specializing in statistical mechanics, stochastic processes, and chaos theory.
In 1978, Collet received a doctorate under Jean-Pierre Eckmann at the University of Geneva, with a thesis entitled Étude du modèle hiérarchique par le groupe de renormalisation.[1] Collet is currently Director of Research of the CNRS at the École polytechnique.[2]
Collet is known for mathematically exact investigations of several model systems in statistical mechanics and chaos theory. He was an Invited Speaker of the ICM in 1998 in Berlin.[3]
He is not to be confused with the University of Strasbourg's Pierre Collet, who specializes in artificial evolution and complex systems. https://cstb.icube.unistra.fr/index.php/Pierre_Collet
