3-Dimensional TQFTs From Non-Semisimple Modular Categories
Marco De Renzi, Azat M. Gainutdinov, Nathan Geer +2
We use modified traces to renormalize Lyubashenko's closed 3-manifold invariants coming from twist non-degenerate finite unimodular ribbon categories. Our construction produces new…

Davydov-Yetter cohomology, comonads and Ocneanu rigidity
Azat M. Gainutdinov, Jonas Haferkamp, Christoph Schweigert
Davydov-Yetter cohomology classifies infinitesimal deformations of tensor categories and of tensor functors. Our first result is that Davydov-Yetter cohomology for finite tensor ca…
