Sondre Kvamme (Bonn), Adjoint triples and Gorenstein projective objects in functor categories.

Abstract:
Given a well-behaved adjoint triple between two abelian categories A and B, we obtain a description of the Gorenstein projective objects in A in terms of the Gorenstein projective objects in B. We apply this to tensor product of algebras and to representations of quivers (with relations) in abelian categories.
