Harald Geppert

from Wikipedia, the free encyclopedia

Harald Aloysius August Maria Geppert (born March 22, 1902 in Breslau , † May 4, 1945 in Berlin ) was a German mathematician.

Life

Geppert was the son of a high school principal and studied mathematics in Breslau and Göttingen from 1920 to 1924 and received his doctorate in 1923 under Adolf Kneser in Breslau ( development of arbitrary functions according to functional theory methods ). He was an assistant at the mathematics seminar in Giessen, was a private lecturer after his habilitation in 1925 and, from 1930, an associate professor at the University of Giessen. In 1935 he became a full professor in Giessen. 1940 to 1945 he was a full professor at the University of Berlin.

Among other things, he dealt with the geometry of circles and spheres (convex geometry) and differential equations (asymptotic behavior of the eigenvalues ​​in boundary value problems), algebraic geometry (where he followed on from the Italian school) and genetics. Following his occupation with the work of Carl Friedrich Gauß , he dealt with the arithmetic-geometric mean and he also published works by Gauß (and on elliptical module functions from the estate) for Ostwald's classics. In the Gauss edition he wrote a commentary on Gauß's work in mechanics and potential theory. Influenced by Tullio Levi-Civita , he dealt with adiabatic invariants.

Geppert, who had an Italian mother (Ernesta Belardi), also published in Italian. 1928/29 he was on a Rockefeller scholarship at the University of Rome.

He was a staunch National Socialist and a member of the SA and the Nazi teachers' association . He was connected to the representative of German mathematics Ludwig Bieberbach , who had helped him to his post in Berlin and used him to establish international contacts. From 1939 he took over the publication of the Zentralblatt für Mathematik and the yearbook on the progress of mathematics . He committed suicide at the end of World War II. Henry Görtler was one of his doctoral students .

In 1931 he married Hedwig Winkler (1903–1945) in Dortmund.
