Relative cohomology of complexes II: Vanishing of relative cohomology

Z Liu, Z Di, B Lu - Journal of Algebra, 2021 - Elsevier
Let R be a ring such that (GP, GP⊥) forms a cotorsion pair cogenerated by a set, where GP
denotes the category of all Gorenstein projective R-modules. Recently, the first author …

[HTML][HTML] Relative cohomology of complexes

Z Liu - Journal of Algebra, 2018 - Elsevier
Let R be an arbitrary ring and C a complex with finite Gorenstein projective dimension (that
is, the supremum of Gorenstein projective dimension of all R-modules in C is finite). For …

Dimension of complexes related to special Gorenstein projective precovers (II)

Z Liu, M Pengju - Communications in Algebra, 2023 - Taylor & Francis
Let R be a ring and X a complex of R-modules. We give some characterizations of the
dimension of X related to special Gorenstein projective precovers. Let R be a ring such that …

FP-injective dimensions and Gorenstein homology

G Yang, J Wang - Proceedings of the Edinburgh Mathematical …, 2022 - cambridge.org
Let $ R $ be a left coherent ring. It is proven that if an $ R $-module $ M $ has a finite FP-
injective dimension, then the Gorenstein projective (resp. Gorenstein flat) dimension and the …

The orthogonal complement relative to the functor extension of the class of all Gorenstein projective modules

M Tamekkante - 2010 - projecteuclid.org
In this paper, we study the pair (GP(R),GP(R)^⊥) where GP(R) is the class of all Gorenstein
projective modules. We prove that it is a complete hereditary cotorsion theory, provided …

Relative cohomology of complexes based on cotorsion pairs

L Zhongkui, X Zongyang - Journal of Algebra and Its Applications, 2020 - World Scientific
Let R be an associative ring with identity. The purpose of this paper is to establish relative
cohomology theories based on cotorsion pairs in the setting of unbounded complexes of …

Dimension of complexes related to special Gorenstein projective precovers

Z Liu, J Li - Communications in Algebra, 2022 - Taylor & Francis
Let R be a ring and X a complex of R-modules. We investigate the relationship between the
dimensions Gppd (X) and Gpd (X) of X, where Gppd (X) is the dimension related to special …

Balance for relative cohomology of complexes

Z Di, B Lu, J Zhao - Journal of Algebra and Its Applications, 2020 - World Scientific
Let R be an arbitrary ring. We use a strict 𝒲 𝒳-resolution X of a complex K with finite#-𝒳 ̃-
projective dimension, where 𝒳 denotes a subcategory of right R-modules closed under …

Let (𝒳, 𝒴) be a complete and hereditary cotorsion pair in a bicomplete abelian category 𝒜.
We introduce a Gorenstein category 𝒢 (𝒳) and 𝒢 (𝒳)-resolution dimension of complexes …

Gorenstein AC-projective dimension of unbounded complexes

Z Di, X Zhang, J Chen - Communications in Algebra, 2017 - Taylor & Francis
Recently, the notion of Gorenstein AC-projective (resp., Gorenstein AC-injective) modules
was introduced in by which the so-called “Gorenstein AC-homological algebra” was …
