François Ledrappier
François Ledrappier (* around 1946) is a French mathematician.
Ledrappier graduated from the Ecole Polytechnique in 1967 and received his PhD from the University of Paris VI in 1975 with Jacques Neveu . He taught at the University of Paris VI and is a professor at the University of Notre Dame , where he has now retired.
He deals with geometric group effects, for example in geodetic flows on compact manifolds of negative curvature and other dynamic systems and in random walks . His investigations are related to ergodic theory and geometric dimension theory.
In 2016 he received the Sophie Germain Prize .
In 1994 he was invited speaker at the International Congress of Mathematicians in Zurich ( Application of dynamics to compact manifolds of negative curvature ).
Nalini Anantharaman is one of his PhD students .
