Pierre Lelong (mathematician)
Pierre Lelong (born March 14, 1912 in Paris ; † October 12, 2011 ) was a French mathematician who dealt with analysis .
Life
Lelong studied from 1931 to 1934 at the École normal supérieure . From 1938 he was a researcher at the CNRS , in 1941 he received his doctorate . From 1940 to 1942 he was Chargé de Conférences at the Faculté de Sciences in Paris and then until 1944 Chargé de Cours at the University of Grenoble (then Faculté des Sciences), which then experienced an upswing when Louis Néel with his Strasbourg laboratory during the war dodged there. From 1946 to 1954 he was professor (for mechanics ) at the University of Lille (Faculté des Sciences). He was then a professor in Paris, later at the University of Paris VI (Pierre et Marie Curie), since 1981 as professor emeritus.
From 1959 to 1961, Lelong was with Guy Camus adviser to President De Gaulles on national education, research and public health, with Lelong placing particular emphasis on the university-industry connection he had experienced and supported in Grenoble. From 1960 to 1964 he was one of the twelve wise men who advised the president on research policy, and from 1961 to 1963 its director. Also in the 1960s, he was president of the state's two-year research plans on several occasions. 1962 to 1966 he was on the board of directors of the CNRS and chairman of the mathematics department. He was involved in the founding of the IRIA (Institute for Computer Science and Automation) and the DRME and was President of the Center International de Calcul de Rome.
Lelong dealt in particular with potential theory and function theory of several complex variables. In 1942 he introduced the concept of the pluriharmonic function and in 1950 founded the metric investigation of complex analytical sets . In the 1960s he introduced the term positive closed currents ("courants"). For a long time he led a well-known analysis seminar in Paris, later together with Pierre Dolbeault and his student Henri Skoda . The contributions to the seminar were published by Springer in its “Lecture Notes in Mathematics” series.
Since 1980 he has been a corresponding member and since 1985 a member of the French Academy of Sciences . In 1950 he received their Prix Eugène Dickson and in 1967 their Prix Ernest Déchelle. In 1972 he received the Grand Prix for Mathematics and Physics. He was Commander of the Legion of Honor , Officer of the Palmes Académiques , Knight of the Order for Services to Health Care , Commander of the Order of the Sun of Peru and the Order of the Black Star . In 1963 he was President of the Société Mathématique de France .
He was an honorary doctorate from Uppsala University .
Lelong was married to the mathematician Jacqueline Lelong-Ferrand from 1947 to 1977 .
