Homological Aspects of (Co)Torsion Functors over Artin Algebras

Abstract: In this talk I will completely determine the derived functors (both left and right) of both torsion and cotorsion functors defined on the module category of an arbitrary artin algebra. The obtained results hold even in greater generality. No prior knowledge of (co)torsion or functor categories is assumed.

The talk is based on joint work with Jeremy Russell.
