Semisimplifying categorical Heisenberg actions and periodic equivalences
Chris Hone, Finn Klein, Bregje Pauwels +3
We systematically apply semisimplification functors in modular representation theory. Motivated by the Duflo--Serganova functor in Lie superalgebras, we construct various functors…
Monoidal Abelian Envelopes with a quotient property
Kevin Coulembier, Pavel Etingof, Victor Ostrik +1
We study abelian envelopes for pseudo-tensor categories with the property that every object in the envelope is a quotient of an object in the pseudo-tensor category. We establish a…
Gluing Approximable Triangulated Categories
Jesse Burke, Amnon Neeman, Bregje Pauwels
Given a bounded-above cochain complex of modules over a ring, it is standard to replace it by a projective resolution, and it is classical that doing so can be very useful. Recentl…
The Gerstenhaber structure on the Hochschild cohomology of a class of special biserial algebras
Joanna Meinel, Van C. Nguyen, Bregje Pauwels +2
We determine the Gerstenhaber structure on the Hochschild cohomology ring of a class of self-injective special biserial algebras. Each of these algebras is presented as a quotient…
Quasi-Galois theory in symmetric-monoidal categories
Bregje Pauwels
Given a ring object in a symmetric monoidal category, we investigate what it means for the extension to be (quasi-)Galois. In particular, we define sp…
