Philippe Tchamitchian

Philippe Tchamitchian (* 1957 ) is a French mathematician who specializes in analysis.

Tchamitchian studied from 1977 to 1982 at the École normal supérieure de Saint-Cloud with the Agrégation in 1980 and received his doctorate in 1983 at the University of Paris-Süd under Yves Meyer . In 1990 he completed his habilitation at the University of Aix-Marseille. From 1991 he became maître de conférences and later professor there. From 1995 to 1999 he headed the laboratory for pure and applied mathematics there. From 2005 to 2008 he was President of the University of Paul-Cézanne-Aix-Marseille 3 and from 2009 to 2011 he was provisional administrator of the University of Sud Toulon-Var. He then held a leading position in the French evaluation organization for research and university teaching AERES and then in HCERES (Haut Conseil de l'évaluation de la recherche et de l'enseignement supérieur). In 2016 he became President of the Comue (Communauté d'universités et établissements) Université Paris Est.

In 2002, together with Pascal Auscher , Michael T. Lacey , Alan McIntosh and Steve Hofmann , he solved the Kato root problem for elliptic differential operators, which had been open since 1953 .

He is also concerned with harmonic analysis, singular integral operators and wavelet transformations.
