Max Koecher (born January 20, 1924 in Weimar ; † February 7, 1990 in Lengerich ) was a German mathematician .

Life

Koecher grew up in Apolda as the only child of a merchant. He attended elementary school and grammar school in Apolda and obtained his school-leaving certificate in 1942 before he was called up for military service. After falling into American captivity in 1944, he was released two years later.

He then studied mathematics and physics at the Georg-August University in Göttingen . In 1951 he received his doctorate there with the work on Dirichlet series with functional equation under Max Deuring , but the dissertation was supervised by Hel Braun . He completed his habilitation in 1954 at the Westphalian Wilhelms University in Münster . From 1962 to 1970 Koecher held a professorship at the University of Munich until he returned to Münster in 1970 as the successor to Hans Petersson . He retired in 1989.

His main research area was the theory of Jordan algebras , on which he published numerous papers. He became internationally known through the discovery of the so-called Koecher effect in the theory of Siegel modular forms. In 1970 he was invited speaker at the International Congress of Mathematicians in Nice ( Jordan algebras and differential geometry ).

He also dealt with geometric issues related to the Castel del Monte .
