-Gorenstein -complexes

B Lu, J Wei, Z Di - 2019 - projecteuclid.org
Given an integer N≧2 and a self-orthogonal subcategory W of an abelian category A, we
investigate the W-Gorenstein N-complexes. We show that an N-complex G is W-Gorenstein …

$\V\W $-Gorenstein categories

G Zhao, J Sun - Turkish Journal of Mathematics, 2016 - journals.tubitak.gov.tr
Let $\A $ be an abelian category, and $\V $, $\W $ two additive full subcategories of $\A $.
We introduce and study the $\V\W $-Gorenstein subcategory of $\A $, which unifies many …

Cartan-Eilenberg N-complexes with respect to self-orthogonal subcategories

B Lu, Z Di, Y Liu - Frontiers of Mathematics in China, 2020 - Springer
Let R be an arbitrary associated ring. For an integer N⩾ 2 and a self-orthogonal subcategory
WW of R-modules, we study the notion of Cartan-Eilenberg W WN-complexes. We show that …

Stability of Gorenstein flat categories with respect to a semidualizing module

Z Di, Z Liu, J Chen - 2015 - projecteuclid.org
We first introduce in the paper the W_F-Gorenstein modules to establish the following Foxby
equivalence: \xymatrix@C=80ptG(F)∩A_C\ar@\lt0.5ex>r^C⊗_R-\amp\,\,\,\,G(W_F)\ar@\lt0 …

One-sided Gorenstein subcategories

W Song, T Zhao, Z Huang - Czechoslovak Mathematical Journal, 2020 - Springer
We introduce the right (left) Gorenstein subcategory relative to an additive subcategory CC
of an abelian category AA, and prove that the right Gorenstein subcategory rG (G (C) G (C)) …

[HTML][HTML] n-Abelian quotient categories

P Zhou, B Zhu - Journal of Algebra, 2019 - Elsevier
Let C be an (n+ 2)-angulated category with an n-suspension functor Σ n and X be a cluster-
tilting subcategory of C. Then we show that the quotient category C/X is an n-abelian …

Relative Gorenstein objects in abelian categories

V Becerril, O Mendoza, V Santiago - Communications in Algebra, 2020 - Taylor & Francis
Let A be an abelian category. For a pair (X, Y) of classes of objects in A, we define the weak
and the (X, Y)-Gorenstein relative projective objects in A. We point out that such objects …

Gorenstein objects in the category of -complexes

B Lu - Journal of Algebra and Its Applications, 2021 - World Scientific
For an integer N≥ 2 and three subcategories 𝒲, 𝒳, 𝒴 of modules, we study the notion of (𝒲,
𝒳, 𝒴)-Gorenstein N-complexes. We show that under certain hypotheses, an N-complex C is …

Gorenstein global dimensions relative to balanced pairs

L Haiyu, Z Rongmin, G Yuxian - Electronic Research Archive, 2020 - aimsciences.org
Let G (X) and G (Y) be Gorenstein subcategories induced by an admissible balanced pair
(X, Y) in an abelian category A. In this paper, we establish Gorenstein homological …

Special precovered categories of Gorenstein categories

T Zhao, Z Huang - Science China Mathematics, 2019 - Springer
Let A be an abelian category and P (A) be the subcategory of A consisting of projective
objects. Let C be a full, additive and self-orthogonal subcategory of A with P (A) a generator …
