Joachim Weidmann

from Wikipedia, the free encyclopedia

Joachim Weidmann (born October 2, 1939 in Eßlingen am Neckar ) is a German mathematician and professor at the Johann Wolfgang Goethe University in Frankfurt .

Life

From 1946 to 1953 he attended the elementary school Westhausen in the district of Aalen and from 1953 to 1958 the Aufbaugymnasium Schwäbisch Gmünd with Abitur in March 1958. This was followed by mathematics studies at the TH Stuttgart (1958–1959) and at the University of Heidelberg (1959–1964) , where he completed his diploma under Konrad Jörgens in March 1964 . After a stay abroad at the Courant Institute (August 1964 - May 1965), he received his doctorate in 1966 in Heidelberg under Konrad Jörgens on the subject of the spectrum theory of Sturm-Liouville operators . In 1968 he moved to the University of Munich , where he completed his habilitation in 1969. From April 1971 he was a professor at the Johann Wolfgang Goethe University in Frankfurt. There he took over the office of Dean of the Mathematics Department (1976–1978, 1989–1990, 1999–2000) and Vice President (1990–1994). In 1994, Weidmann led the office of President of the University of Frankfurt for several months because the new elections had failed.

The most important of his mathematical achievements are the work on the absolutely continuous spectrum and the oscillation theory of Sturm-Liouville operators .
