Generalized negligible morphisms and their tensor ideals
Thorsten Heidersdorf, Hans Wenzl
We introduce a generalization of the notion of a negligible morphism and study the associated tensor ideals and thick ideals. These ideals are defined by considering deformations o…

Monoidal abelian envelopes and a conjecture of Benson--Etingof
Kevin Coulembier, Inna Entova-Aizenbud, Thorsten Heidersdorf
We give several criteria to decide whether a given tensor category is the abelian envelope of a fixed symmetric monoidal category. As a main result we prove that the category of fi…

Homotopy quotients and comodules of supercommutative Hopf algebras
Thorsten Heidersdorf, Rainer Weissauer
We study induced model structures on Frobenius categories. In particular we consider the case where is the category of comodules of a supercommutative Hopf algebra $A…
