Joint Seminar

This a joint online video seminar series on theoretical and mathematical physics organized together by the ASC and the universities of Heidelberg, Mainz and Vienna via a BigBlueButton interface.

Please note the change of time:
It will take place on Mondays at 16:15.

17.01. Daniel Roggenkamp (U. Mannheim) (via ZOOM)
Title: Defects and affine Rozansky-Witten models
Abstract: In this talk I will explain in the example of Rozansky-Witten models with affine target spaces, how, by means of the cobordism hypothesis, one can reconstruct an (extended) TQFT from its identity defect. For illustration I will shoot a sparrow with a cannon and use defects to rederive the state spaces of affine RW models for arbitrary surfaces.
