Physical Math Seminar @ MPIM
Organized by David Aretz, Peter Teichner and myself. Contact: {aretz, prinz, teichner}@mpim-bonn.mpg.de
A seminar about different topics in Mathematical Physics, broadly around Quantum Field Theory, Algebraic Topology and Differential Geometry. We host research talks as well as review talks.
Official MPIM seminar webpage and program overview.
If not stated otherwise, we meet Thursdays at 12:00 a.m. in the MPIM Lecture Hall (see the exceptions below).
Summer Term 2024
In August 2024, this seminar was combined with the one-month QFT Workshop that took place at the MPIM. Currently, we aim to understand this Preprint via some appropriate review talks.
