"Simple functors of group categories"

By

Laurence Barker

Abstract: This joint work with Robert Boltje is
from a preliminary part of a paper we are preparing on blocks of certain kinds
of group categories. We shall introduce the notion of an admissible group
category, generalizing Serge Bouc's notion of
admissibility in such a way as to include Mackey categories associated with fusion
systems, and also the biset categories discussed in
recent seminars by Nadia Romero. We shall classify the simple functors of an admissible
group category.  The material can be
regarded as a pedagogical illustration of a routine technique, since the proofs
are variants of well-known proofs of similar classifications of simple
functors.
