Representations of matched pairs of groupoids and applications to weak Hopf algebras

open access: yes, 2004
We introduce the category of set-theoretic representations of a matched pair of groupoids. This is a monoidal category endowed with a monoidal functor to the category of quivers over the common base of the groupoids in the matched pair (the forgetful functor).

An application of Hopf-algebra techniques to representations of finite classical groups

open access: yesJournal of Algebra, 1991
The goal of this paper is to develop a Hopf algebra approach to representation theory of classical groups over finite fields. For the case of general liner groups this was made by \textit{A. V. Zelevinsky} [Representations of finite classical groups, a Hopf algebra approach (Lect. Notes Math. 869, 1981; Zbl 0465.20009)].

The stable Picard group of Hopf algebras via descent, and an application

open access: yes, 2016
Let $A$ be a cocommutative finite dimensional Hopf algebra over the field with two elements, satisfying some mild hypothesis. We set up a descent spectral sequence which computes the Picard group of the stable category of modules over $A$. The starting point is the observation that the stable category of $A$-modules can be reconstructed, as an $\infty$-
