GeSAMT — Gemeinsames Seminar Algebra und Modelltheorie

The Bonn-Münster-Düsseldorf GeSAMT (Gemeinsames Seminar Algebra und Modelltheorie) takes place on a few times per year, each consisting of about 3 talks on various subjects around algebra and model theory.
The location usually alternates between Bonn, Düsseldorf and Münster.
For any questions and to receive announcements about the seminar, please contact either Florian Felix (Düsseldorf), Silke Meißner (Münster), Zahra Mohammadi (Münster), Blaise Boissonneau (Düsseldorf), or Immanuel Halupzcok (Düsseldorf).

Bonn, Düsseldorf and Münster are also part of the wider region participating in the Regional days in Model Theory and Applications.
