Monomorphism categories, cotilting theory, and Gorenstein-projective modules
P Zhang - Journal of Algebra, 2011 - Elsevier
The monomorphism category S n (X) is introduced, where X is a full subcategory of the
module category A-mod of an Artin algebra A. The key result is a reciprocity of the …

Gorenstein-projective modules over triangular matrix Artin algebras
BL Xiong, P Zhang - Journal of Algebra and its Applications, 2012 - World Scientific
Let be an Artin algebra. Under suitable conditions, we describe all the modules in⊥ Λ, and
obtain criteria for the Gorensteinness of Λ. As applications, we determine explicitly all the …

Homotopy equivalences induced by balanced pairs
XW Chen - Journal of Algebra, 2010 - Elsevier
We introduce the notion of balanced pair of additive subcategories in an abelian category.
We give sufficient conditions under which a balanced pair of subcategories gives rise to a …

A construction of Gorenstein-projective modules
ZW Li, P Zhang - Journal of Algebra, 2010 - Elsevier
We determine all the Gorenstein-projective modules over the T2-extension of a Gorenstein
algebra, and over (AM0B), where A and B are self-injective algebras, and M is an AB …

[HTML][HTML] From CM-finite to CM-free
F Kong, P Zhang - Journal of Pure and Applied Algebra, 2016 - Elsevier
We prove a generalization of the stability for Gorenstein categories in [36] and [24]; and
show that the relative Auslander algebra of a CM-finite algebra is CM-free. On the other …
