摘要：An algebra A is left weakly Gorenstein if any semi-Gorenstein-projective left A-modules is Gorenstein-projective. The weakly Gorensteinness of a kind of algebras is answered. Using the method of the monomorphism category, it is proved that the tensor algebra A⊗B with gl.dimB<∞ is left weakly Gorenstein if and only if so is A. This is based on the joint work with Pu Zhang and Shijie Zhu.
