Semiorthogonal decompositions for representations of algebraic groups
Monday 01 September to Wednesday 03 September 2025
Semiorthogonal decompositions are a well-established tool for the study of derived categories in algebraic geometry and in the representation theory of Artin algebras. The goal of this meeting is to discuss semiorthogonal decompositions that arise in the representation theory of algebraic groups, going over the main proofs of the recent work arXiv:2407.13653 of Samokhin and van der Kallen, and exploring emerging connections to geometric representation theory.
After the end of the workshop, participants will have the possibility for informal discussions as well as presentations of research talks on Thursday, September 4.
Location: Bielefeld University
Organisers: Wassilij Gnedin, Henning Krause, Eike Lau, Charles Vial
