Paul Dubreil

Paul Dubreil (* March 1, 1904 in Le Mans, † 9 March 1994 in Soisy -sur -École in Paris) was a French number theorist.

Dubreil was the son of a maths school teacher at Le Mans in 1923 and studied at the École Normale Supérieure (ENS ) and the Sorbonne. After he was first nationwide competition for the aggregation in 1926, he became a lecturer at the ENS and received his doctorate in 1930, but stayed before and after usually provided with a Rockefeller fellowship at the University of Hamburg with Emil Artin on. Here he met Emmy Noether, which he also followed to Gottingen ( where he worked with the Noether students Bartel Leendert van der Waerden ) and Frankfurt. He also studied in Rome at the leading Italian algebraic geometers Guido Castelnuovo, Federigo Enriques and Francesco Severi. Back in France, he went to the University of Lille in 1931 and 1933 at the University of Nancy. In 1946 he went to the Sorbonne, where he became in 1954 Professor of number theory.

Dubreil dealt with algebra ( semigroups ), algebraic geometry and number theory. He had ( originally founded by Albert Chatelet ) with Charles Pisot from the 1950s, a seminar in Paris on algebra and number theory and was also in the 1940s, short time member of Nicolas Bourbaki.

Since 1930, he was with the mathematician Marie -Louise Jacotin ( 1905-1972 ) married, with whom he also worked together mathematically ( they published under Jacotin - Dubreil ).
