Abstract

Let C be a semidualizing complex over a noetherian local ring A. If there exists a local homomorphism AB vanishing at the level of the first Koszul homology modules (e.g. the Frobenius endomorphism in positive characteristic, or any homomorphism factorizing through a regular local ring) and of finite Gorenstein dimension relative to C, then C is dualizing.

Keywords: Dualizing complex; derived reflexivity; Gorenstein dimension
