Hennings TQFTs for Cobordisms Decorated With Cohomology Classes

Marco De Renzi, Jules Martel, Bangxin Wang

Starting from an abelian group and a factorizable ribbon Hopf -bialgebra , we construct a TQFT for connected framed cobordisms between connected surfaces with conne…

Algebraic Presentation of -Dimensional -Handlebodies and -Dimensional Cobordisms

Anna Beliakova, Ivelina Bobtcheva, Marco De Renzi +1

In this paper, we give a new direct proof of a result by Bobtcheva and Piergallini that provides finite algebraic presentations of two categories, denoted and $4\ma…

Kerler-Lyubashenko Functors on 4-Dimensional 2-Handlebodies

Anna Beliakova, Marco De Renzi

We construct a braided monoidal functor from Bobtcheva and Piergallini's category of connected 4-dimensional 2-handlebodies (up to 2-deformations) to an arbitr…

Modular Categories and TQFTs Beyond Semisimplicity

Christian Blanchet, Marco De Renzi

Vladimir Turaev discovered in the early years of quantum topology that the notion of modular category was an appropriate structure for building 3-dimensional Topological Quantum Fi…

Mapping Class Group Representations From Non-Semisimple TQFTs

Marco De Renzi, Azat M. Gainutdinov, Nathan Geer +2

In [arXiv:1912.02063], we constructed 3-dimensional Topological Quantum Field Theories (TQFTs) using not necessarily semisimple modular categories. Here, we study projective repres…

Non-Semisimple 3-Manifold Invariants Derived From the Kauffman Bracket

Marco De Renzi, Jun Murakami

We recover the family of non-semisimple quantum invariants of closed oriented 3-manifolds associated with the small quantum group of using purely combinatorial me…
