Hans Petersson
Hans Petersson (born September 24, 1902 in Bentschen in what was then the Prussian province of Posen ; † November 9, 1984 in Münster ) was a German mathematician .
After graduating from high school, Petersson studied mathematics and astronomy at the University of Hamburg , where he received his doctorate under Erich Hecke in 1925 and completed his habilitation in 1929. At first he stayed in Hamburg as a private lecturer. After the " seizure of power " by the National Socialists , on November 11, 1933, he signed the confession of the German professors to Adolf Hitler . In 1936 he became an associate professor in Hamburg. Petersson became a member of the NSDAP on May 1, 1937 . In 1939 he took over a professorship at the Karl Ferdinand University in Prague. In 1941 he followed a call to the University of Strasbourg before returning to Hamburg in 1944. There he initially worked as a dietician in the post-war period . In 1953 he accepted an appointment at the Westphalian Wilhelms University in Münster, where he retired as a professor in 1970. In 1982 he received an honorary doctorate from Bielefeld University .
Petersson worked mainly in the areas of function theory , algebraic geometry and analytic number theory .
The Petersson scalar product , which plays an important role in the theory of modular forms, is named after him . He also made a generalization of the Ramanujan conjecture (Petersson-Ramanujan conjecture).
Petersson married Margarethe, b. Ehlers (1903-1994) in Hamburg. Went out of wedlock Jörn Petersson (* 1936), em. Professor of Technical Physics at Saarland University , and Holger P. Petersson , em. Professor of Mathematics at the Fernuniversität in Hagen .
