Semisimplifications and representations of the General Linear Supergroup
Thorsten Heidersdorf, Rainer Weissauer
We study the semisimplification of the full karoubian subcategory generated by the irreducible finite dimensional representations of the algebraic supergroup over an alge…

Gruson-Serganova character formulas and the Duflo-Serganova cohomology functor
Maria Gorelik, Thorsten Heidersdorf
We establish an explicit formula for the character of an irreducible finite-dimensional representation of . The formula is a finite sum with integer coefficient…

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…
