Wed, 01/06/2022 - 16:00 - 17:30 Rozansky-Witten models are candidates for 3-dimensional topological

functorial field theories, constructed from non-semisimple data. Based

on a path integral analysis, Kapustin and Rozansky proposed a rich 3-

categorical structure that is expected to govern all Rozansky-Witten

models and their defects. By truncation and restriction to affine

geometries and their orbifolds, one obtains a symmetric monoidal

(\infty,2)-category C. With the help of the cobordism hypothesis, we

classify and explicitly compute extended TQFTs with values in C.
