Invariants of a Free Linear Category and Representation Type

arXiv:1507.02842 · doi:10.1016/j.jpaa.2016.02.007

Abstract

We consider an homogeneous action of a finite group on a free linear category over a field in order to prove that the subcategory of invariants is still free. Moreover we show that the representation type is preserved when considering invariants.
