Oberseminar "String Theory and Beyond the Standard Model"

Monday, 2:00 pm, seminar room in Philosophenweg 19, common lunch from 1:00 pm

To facilitate the sharing of papers and for speaker from far away, the seminar will often take place in the personal room of A. Hebecker on Zoom. If no talk is announced, we will discuss recent papers in an informal style.
