Wolfgang Hahn (mathematician)

from Wikipedia, the free encyclopedia

Wolfgang Hahn (born April 30, 1911 in Potsdam , † January 10, 1998 in Kassel ) was a German mathematician and professor at the Graz University of Technology .

Life

From 1928 Wolfgang Hahn studied mathematics at the universities in Berlin and Göttingen . In 1933 he did his doctorate with Issai Schur on the subject of the zeros of the Laguerre and Hermitian polynomials . After that he was in school service until he was drafted into the Wehrmacht in 1940. He became a prisoner of war and did not return to Berlin until 1946. While he was employed as an industrial worker, he completed his habilitation in 1950 at the University of Berlin and in 1952 received a lectureship at the TH Braunschweig , where he worked with interruptions until 1963. From 1959 to 1961 he took leave of absence to attend the Indian Institute of Technology Madrasto build a Department of Applied Mathematics. Between 1962 and 1964 he worked at various American universities and received a position as a scientific adviser at the University of Bonn . On October 1, 1964, he took over the chair for Mathematics II at the Graz University of Technology, where he stayed until his retirement in 1981. From 1967 to 1969 he was Dean of the Faculty of Natural Sciences, Rector 1969/70 and then Vice Rector until 1972.

After his wife's death in 1982, he lived in Graz until 1997 and then moved to Kassel with his children, where he died in early January 1998 as a result of a tumor operation.

research

He worked on special functions and in particular orthogonal polynomials . The Hahn polynomials are named after him.
