Abstract
For a dualizing module over a commutative Noetherian ring with identity, it is known that its Auslander class (respectively, Bass class ) is characterized as those -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 Noetherain rings.
