3-dimensional TQFTs from derived categories of quantum group representations
Cris Negron
For any finite modular tensor category A, we show that the associated derived -category D(A) supports a topological quantum field theory in dimension 3. This TQFT takes the…

Cocompletions for non-abelian vertex tensor categories
Robert McRae, Cris Negron
It was recently shown by Huang that the category of -cofinite modules for any vertex operator algebra admits a natural braided monoidal structure. Here, we show that this…

Cochain valued TQFTs from nonsemisimple modular tensor categories
Agustina Czenky, Cris Negron
We show that a vector space valued TQFT constructed in work of De Renzi et al. [DGGPR23] extends naturally to a topological field theory which takes values in the symmetric monoida…
