Group seminar on higher geometric structures and mathematical physics

This is the web page for the group seminar for students and postdocs working on higher geometric structures and mathematical physics, organized by Christian Blohmann [1], Lory Aintablian [2], and Annika Tarnowsky [3]. Seminar participation is by invitation. In the summer semester 2024, the meetings take place on Wednesdays from 10:30-12:00h in the lecture hall of MPIM. This group seminar is complemented by the Higher differential geometry seminar [4], where research or more advanced talks are given.
