Algebras in fusion categories: species and hereditary algebras
Edmund Heng, Mateusz StroiÅski
We initiate the study of non-semisimple algebras in fusion categories by establishing the framework of -species -- analogous to the framework of species and quivers us…
Hochschild cohomology for finitary 2-representations
James Macpherson, Vanessa Miemietz, Mateusz StroiÅski
In this article, we define and investigate Hochschild cohomology for finitary 2-representations of quasi-fiat 2-categories.
A Coboundary Temperely-Lieb Category for -Crystals
Moaaz Alqady, Mateusz StroiÅski
By considering a suitable renormalization of the Temperley--Lieb category, we study its specialization to the case . Unlike the case, the obtained monoidal category,…
Simple algebras and exact module categories
Kevin Coulembier, Mateusz StroiÅski, Tony Zorman
We verify a conjecture of Etingof and Ostrik, stating that an algebra object in a finite tensor category is exact if and only if it is a finite direct product of simple algebras. T…
