Szolem Almond Brojt

Szolem Mandelbrojt (born January 10, 1899 in Warsaw , † September 23, 1983 in Paris ) was a French mathematician with Jewish-Polish roots who dealt with analysis .

Mandelbrojt's ancestors came from Lithuania. He studied in Warsaw and Kharkov , where he was particularly influenced by Sergei Bernstein . He continued his studies in Paris (among others with Édouard Goursat , Henri Lebesgue , Paul Montel , Émile Picard ) and received his doctorate in 1923 at the Sorbonne with Jacques Hadamard . With Hadamard he published a book on the Taylor series . From 1924 to 1926 he was on a Rockefeller Scholarship in the USA, where he was a lecturer at Rice University in Houston from 1926 to 1927. In 1928 he was maître de conférences at the Université Lille Nord de France and in 1929 professor in Clermont-Ferrand , where he was a colleague of René de Possel . He and Possel attended seminars every other Monday at the Institut Henri Poincaré in Paris. Through contact with old college friends, it emerged that both were early members of Bourbaki in the 1930s . Mandelbrojt was interested in classical analysis. With Henri Cartan he worked on harmonic analysis and in 1935 published the book Séries de Fourier et Classes quasi-analytiques de Fonctions . In 1938 he became a professor at the Collège de France , but had to leave France after the occupation by German troops in 1940 and went back to Rice University in Houston. There he published Analytic functions and classes of infinitely differentiable functions in 1942 and his lectures on Dirichlet series in 1944 (in 1969 he published another book on Dirichlet series). Even after returning to his chair at the Collège de France, he remained connected to Rice. In 1972 he retired. With Paul Lévy , Maurice Fréchet and Laurent Schwartz he edited Hadamard's works in the 1960s and wrote his biography with Levy, Malgrange and Malliavin.

In 1950 he was invited speaker at the International Congress of Mathematicians (ICM) in Cambridge (Massachusetts) ( Théorèmes d´unicité de la théorie des fonctions ). In 1953 he was President of the Société Mathématique de France . In 1972 he was accepted into the Académie des Sciences .

His PhD students include Yitzhak Katznelson , Hans Reiter , Paul Malliavin and Jean-Pierre Kahane . Szolem Mandelbrojt was the uncle of the mathematician Benoît Mandelbrot .
