GRK lecture for the summer semester 2020:


Up-date (SARS-CoV-2 pandemic) - 3 June 2020

Due to the SARS-CoV-2 pandemic the activities of the GRK are currently suspended. This concerns in particular the workshop of the GRK and the ring lectures. The ring lecture however takes place as online video lecture. The schedule can be found below. We ask for your understanding for this measure and look forward to returning to normal activities in the future.
