Virtually Gorenstein Artin algebras are weakly Gorenstein
Weiqing Li
We prove that all (possibly infinitely generated) semi-Gorenstein-projective modules over a virtually Gorenstein Artin algebra are Gorenstein projective. We also establish a new cr…

On a proof of the Gorenstein Symmetry Conjecture
Weiqing Li
We give a homological proof of the famous Gorenstein Symmetry Conjecture, which asserts that one-sided finiteness of the self-injective dimension of an Artin algebra is sufficient…
