Rozansky-Witten Models as Extended Defect TQFTs
The Institute for Advanced Study requires that all adult visitors, collaborators, conference and on-campus seminar attendees and outside vendors coming to the Institute are required to have completed a COVID-19 vaccination and booster in order to enter the IAS campus. Individuals must be prepared to present proof of vaccination if asked and are expected to follow the Institute's Covid-19 Procedures. Masks are optional while indoors.

Abstract: Very few examples of extended TQFTs are known explicitly. In this talk I will discuss a very explicit construction of the extended TQFTs associated to Rozanksy-Witten models with affine target spaces. I will furthermore explain how to incorporate defects into the extended TQFTs. This can be used for instance to derive the Hilbert spaces of affine Rozansky-Witten models associated to surfaces with arbitrary insertions of defect networks.
