Joachim Schwermer

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

Joachim Schwermer in Oberwolfach 2010

Schwermer received his Abitur in 1969 at Aloisiuskolleg in Bad Godesberg and then studied mathematics at the University of Bonn. 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 .[2] In 1982 he received his Habilitation from the University of Bonn. 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. In 1987 he was awarded the Gay-Lussac-Humboldt-Prize.

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.

He is now a professor at the University of Vienna as well as the scientific director at the Erwin Schrödinger International Institute for Mathematical Physics.

In June 2016, the Max Planck Institute for Mathematics held a Conference on the Cohomology of Arithmetic Groups on the occasion of Joachim Schwermer's 66th birthday.[4]

gollark: You can't really just force them to add "also the world might not be real" to the uncertainties, and it would be annoying and unhelpful.
gollark: But insisting that people also say "but also the world might not be real" before discussing any scientific thing is helpful, say?
gollark: I mean, yes, but if you don't assume those you can't really... do anything?
gollark: Explaining is hard even if you do know things, sometimes.
gollark: I think I remember his name from something.
