Arnaud Chéritat (born June 7, 1975 ) is a French mathematician who deals with dynamic systems and especially complex dynamics.

Arnaud Chéritat, Oberwolfach 2008

Chéritat attended the Lycée Marcellin Bethelot in St Maur des Fossés (Val de Marne) and studied mathematics from 1995 at the École normal supérieure (Licentiate in Mathematics 1995) and the University of Paris-Süd (DEA 1996), where he studied with Adrien Douady in 2001 received his doctorate (Recherche d'ensembles de Julia de mesure de Lebesgue positive). From 2002 he was Maître de conférences at the University of Toulouse, where he was Chargé de Recherches of the CNRS since 2007 and completed his habilitation in 2008.

He is known for his proof with Xavier Buff of the existence of Julia sets with positive Lebesgue measures in the iteration of quadratic polynomials. They thus proved a suspicion by Douady.

In 2006 he received the Leconte Prize of the Académie des Sciences with Buff . In 2012 he became a Fellow of the American Mathematical Society . In 2010 he was invited speaker at the International Congress of Mathematicians in Hyderabad (India) (Quadratic Julia sets with positive area, with Xavier Buff). In 2008 he received a Starting Grant from the European Research Council with Buff.
