Joachim Schwermer (26 May 1950, Kulmbach^[1]) is a German mathematician, specializing in number theory.

Education

Schwermer received his Abitur in 1969 at Aloisiuskolleg in Bad Godesberg and then studied mathematics at the University of Bonn.^{[citation needed]} After graduating in 1974 with his Diplom, he received in 1977 his Promotion (Ph.D.) underi Günter Harder with thesis Eisensteinreihen und die Kohomologie von Kongruenzuntergruppen von ${\displaystyle SL_{n}(\mathbb {Z} )}$.^[2] In 1982 he received his Habilitation from the University of Bonn.

Career

From 1986 he was a professor at the Catholic University of Eichstätt-Ingolstadt, then at the University of Düsseldorf,^[3] and finally in the 2000s at the University of Vienna. During the academic year 1980–1981 Schwermer was a visiting scholar at the Institute for Advanced Study. He is the scientific director at the Erwin Schrödinger International Institute for Mathematical Physics.

Research

Schwermer's research deals with algebraic groups in number theory, arithmetic geometry, Lie groups, and L-functions. He has written essays on the history of mathematics, for example, about Helmut Hasse, Hermann Minkowski, and Emil Artin.

Awards and honors

In 1987 he was awarded the Gay-Lussac-Humboldt-Prize.
