A refinement of Gorenstein flat dimension via the flat--cotorsion theory
Lars Winther Christensen, Sergio Estrada, Li Liang +3
We introduce a refinement of the Gorenstein flat dimension for complexes over an associative ring--the Gorenstein flat-cotorsion dimension--and prove that it, unlike the Gorenstein…

A Bass equality for Gorenstein injective dimension of modules finite over homomorphisms
Lars Winther Christensen, Dejun Wu
Let be a local ring homomorphism and a finitely generated -module. We prove that if the Gorenstein injective dimension of over is finite, then it equals th…
