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.
The `bonus' part of the meeting commences on Thursday, 13 October, at 2.30pm and ends on Friday, 14 October, at about 12.30pm. The `classic' part starts on Friday, 14 October, at 2.30pm and ends on Saturday, 15 October, at about 1.15pm.
The talks take place in Lecture Halls 5E and 5F as indicated below.
