'''Joachim Schwermer''' (26 May 1950, [[Kulmbach]]<ref>brief biography in [http://library.ias.edu/files/pdfs/ar/annualreportforf1981inst.pdf The Institute for Advanced Study, ''Annual Report for the Fiscal Year July 1, 1980-June 30, 1981''] {{Webarchive|url=https://web.archive.org/web/20111219141051/http://library.ias.edu/files/pdfs/ar/annualreportforf1981inst.pdf |date=December 19, 2011 }} (PDF; 4,6&nbsp;MB), p. 41</ref>) 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]].{{cn|date=May 2024}} After graduating in 1974 with his ''[[Diplom]]'', he received in 1977 his [[Promotion (Germany)|''Promotion'']] (Ph.D.) underi [[Günter Harder]] with thesis ''Eisensteinreihen und die Kohomologie von Kongruenzuntergruppen von <math>SL_n(\mathbb{Z})</math>''.<ref>{{MathGenealogyProject|id=23445|name=Joachim Schwermer}}</ref> 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]],<ref>See the author addresses in ''[https://doi.org/10.1007%2FBF02785578 On the concept of level for subgroups of SL<sub>2</sub> over arithmetic rings]'' (May 1998)</ref> 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]].
