Guy David (mathematician)

from Wikipedia, the free encyclopedia

Guy RP David (born June 1, 1957 in Saint-Omer ) is a French mathematician who specializes in calculus.

David studied at the École normal supérieure in 1976 , received the Agrégation and the DEA and received his doctorate in 1981 from the University of Paris-Süd (Paris XI) under Yves Meyer (Thèse du 3ème cycle). The second part of the doctorate (Thèse d'État) took place in 1986 with Meyer ( Noyau de Cauchy et opérateurs de Caldéron-Zygmund ). From 1982 to 1989 he did research for the CNRS at the École Polytechnique . He has been a professor at the University of Paris-South since 1989 (from 1991 professor 1st class and from 2001 Classe exceptionelle).

David dealt with the theory of singular integral equations according to the theory of Alberto Calderón and with Hardy spaces . Among other things, he dealt with the problem of Painlevé , whose solution by Xavier Tolsa was also based on methods of David. David solved a special case in 1998, the Vitushkin conjecture . With Jean-Lin Journé in 1984 he proved the T (1) theorem, for which they received the Salem Prize . The theorem is of fundamental importance for the theory of singular integral operators of the Calderon-Zygmund type. He also dealt with the presumption of David Mumford and Shah (from the theory of image decomposition) and his contributions to the theory of Hardy spaces contributed to the solution of the continuous (analytical) version of the problem of the traveling salesman by Peter Jones in 1990. He worked with Stephen Semmes , with whom he published several books.

In 2004 he received the Prix ​​Servant and in 1990 the Prix IBM France. In the same year he received the Ferran Sunyer i Balaguer Prize for his book Singular sets of minimizers for the Mumford-Shah functional . From 1996 to 2001 he was a junior member and from 2010 to 2015 a senior member of the Institut Universitaire de France.

In 1986 he was invited to speak at the International Congress of Mathematicians in Berkeley (Opérateurs de Caldéron-Zygmund). In 1999 he was elected to the American Academy of Arts and Sciences .
