Cotilting Modules and Gorenstein Homological Dimensions

ABSTRACT For a dualizing module $D$ over a commutative Noetherian ring $R$ with identity, it is known that its Auslander class $\mathscr {A}_D\left(R\right)$ (respectively, Bass class $\mathscr {B}_D\left(R\right)$) is characterized as those $R$-modules with finite Gorenstein flat dimension (respectively, finite Gorenstein injective dimension). We establish an analogue of this result in the context of cotilting modules over general Noetherian rings.

Abstract

ABSTRACT For a dualizing module $D$ over a commutative Noetherian ring $R$ with identity, it is known that its Auslander class $\mathscr {A}_D\left(R\right)$ (respectively, Bass class $\mathscr {B}_D\left(R\right)$) is characterized as those $R$-modules with finite Gorenstein flat dimension (respectively, finite Gorenstein injective dimension). We establish an analogue of this result in the context of cotilting modules over general Noetherian rings.
