Norddeutsches Gruppentheorie-Kolloquium 2022
13-15 October 2022
Heinrich-Heine-Universität Düsseldorf
After two scaled-down online editions, we are again aiming for an in-person edition of the NDGK. As a bonus, the classic Fr-Sa NDGK-format is enriched by additional Th-Fr activities, which are primarily aimed at doctoral and postdoctoral researchers and which are hosted in cooperation with the local Research Training Group GRK 2240.
