Coinduction functor in representation stability theory

Representation Theory 2016-04-14 v3 Rings and Algebras

Abstract

We study the coinduction functor on the category of FI-modules and its variants. Using the coinduction functor, we give new and simpler proofs of (generalizations of) various results on homological properties of FI-modules. We also prove that any finitely generated projective VI-module over a field of characteristic 0 is injective.
