Maurice Janet

Maurice Janet (1888–1983) was a French mathematician.

Education and career In 1912, as a student he visited the University of Göttingen. He was a professor at the University of Caen. He was an Invited Speaker of the International Congress of Mathematicians in 1924 in Toronto, in 1932 in Zürich, and in 1936 in Oslo.

Named in his honor are Janet bases, Janet sequences and a related algorithm in the theory of systems of partial differential equations. In 1926, he proved results that were later generalized by John Forbes Nash Jr. in his embedding theorem.

In 1948, Janet was the president of the Société Mathématique de France. He was a close friend of the mathematician Ernest Vessiot.
