Jean-Pierre Kahane

Jean-Pierre Kahane (born December 11, 1926 in Paris - † June 21, 2017 ) was a French mathematician .

Life

Jean-Pierre Kahane attended the École normal supérieure and reached the Agrégation in 1949 . He worked at the Center national de la recherche scientifique until 1954 and then received his doctorate with Szolem Mandelbrojt with the dissertation Sur quelquesproblemèmes d'unicité et de prolongement relatifs aux fonctions approchables par des sommes d'exponentielles . He was then a lecturer and then professor at the natural science faculty in Montpellier (1954–1961) and then taught at the Paris-South University in Orsay until his retirement in 1994 . He was President of the Société mathématique de France (1972–1973) and President of the University of Paris-South (1975–1978).

In 1982 he became a corresponding member of the Académie des sciences and in 1998 a full member. In 1995 he was awarded the Picard Medal . In 1972/73 he was President of the Société Mathématique de France .

Kahane's main areas of work were function theory , the theory of Fourier series and functional analysis , in particular the geometry of Banach spaces . The theorem of Gleason-Kahane-Żelazko , a theorem from the theory of Banach algebras , as well as the Kahanian principle of contraction from the theory of bounded operators are associated with his name. ${\ displaystyle {\ mathcal {R}}}$

In 1962 he gave a plenary lecture at the International Congress of Mathematicians in Stockholm ( Transformées de Fourier des fonctions sommables ). He was a fellow of the American Mathematical Society .

His younger brother was the director and screenwriter Roger Kahane (1932-2013).
