Symmetry of self-injective dimensions under the Auslander condition
Dawei Shen
Let be a module-finite algebra over a commutative Noetherian ring. We give a local criterion for the -Gorenstein condition on . As an application, we prove that if sa…

A Serre-type criterion for -Gorenstein rings and its application to Nakayama algebras
Dawei Shen
Let be a left and right Noetherian ring. We introduce a Serre-type condition , formulated in terms of the first occurrence and the flat dimension of indecomposable injec…
