Commutative exact algebras and modular tensor categories

K Shimizu, H Yadav - arXiv preprint arXiv:2408.06314, 2024 - arxiv.org
Inspired by the study of vertex operator algebra extensions, we answer the question of when
the category of local modules over a commutative exact algebra in a braided finite tensor …

CFT correlators and mapping class group averages

I Romaidis, I Runkel - Communications in Mathematical Physics, 2024 - Springer
Mapping class group averages appear in the study of 3D gravity partition functions. In this
paper, we work with 3D topological field theories to establish a bulk-boundary …

Commutative algebras in Grothendieck-Verdier categories, rigidity, and vertex operator algebras

T Creutzig, R McRae, K Shimizu, H Yadav - arXiv preprint arXiv …, 2024 - arxiv.org
Let $ A $ be a commutative algebra in a braided monoidal category $\mathcal {C} $; eg, $ A

Invertible braided tensor categories

A Brochier, D Jordan, P Safronov, N Snyder - Algebraic & Geometric …, 2021 - msp.org
We prove that a finite braided tensor category 𝒜 is invertible in the Morita 4–category BrTens
of braided tensor categories if and only if it is nondegenerate. This includes the case of …

A classification of modular functors via factorization homology

A Brochier, L Woike - arXiv preprint arXiv:2212.11259, 2022 - arxiv.org
Modular functors are traditionally defined as systems of projective representations of
mapping class groups of surfaces that are compatible with gluing. They can formally be …

Homological construction of quantum representations of mapping class groups

M De Renzi, J Martel - arXiv preprint arXiv:2212.10940, 2022 - arxiv.org
We provide a homological model for a family of quantum representations of mapping class
groups arising from non-semisimple TQFTs (Topological Quantum Field Theories). Our …

tilting modules in the mixed case

L Sutton, D Tubbenhauer, P Wedrich, J Zhu - Selecta Mathematica, 2023 - Springer
Using the non-semisimple Temperley–Lieb calculus, we study the additive and monoidal
structure of the category of tilting modules for SL 2 in the mixed case. This simultaneously …
