Homological dimension based on a class of Gorenstein flat modules [PDF]

open access: yesComptes Rendus. Mathématique, 2022
In this paper, we study the relative homological dimension based on the class of projectively coresolved Gorenstein flat modules (PGF-modules), that were introduced by Saroch and Stovicek.

Smashing localizations of rings of weak global dimension at most one [PDF]

open access: yes, 2014
We show for a ring R of weak global dimension at most one that there is a bijection between the smashing subcategories of its derived category and the equivalence classes of homological epimorphisms starting in R. If, moreover, R is commutative, we prove

Gorenstein Rings via Homological Dimensions, and Symmetry in Vanishing of Ext and Tate Cohomology [PDF]

open access: yesAlgebras and Representation Theory, 2023
The aim of this article is to consider the spectral sequences induced by tensor-hom adjunction, and provide a number of new results. Let R be a commutative Noetherian local ring of dimension d .

Homological Dimensions of Local (Co)homology Over Commutative DG-rings [PDF]

open access: yesCanadian mathematical bulletin, 2017
Let $A$ be a commutative noetherian ring, let $\mathfrak{a}\subseteq A$ be an ideal, and let $I$ be an injective $A$ -module. A basic result in the structure theory of injective modules states that the $A$ -module ${{\Gamma }_{\alpha }}\left( I \right ...

On reducing homological dimensions over Noetherian rings [PDF]

open access: yes, 2020
Let $\Lambda$ be a left and right noetherian ring. First, for $m,n\in\mathbb{N}\cup\{\infty\}$, we give equivalent conditions for a given $\Lambda$-module to be $n$-torsionfree and have $m$-torsionfree transpose.

Gorenstein homological algebra and universal coefficient theorems [PDF]

open access: yes, 2017
We study criteria for a ring—or more generally, for a small category—to be Gorenstein and for a module over it to be of finite projective dimension. The goal is to unify the universal coefficient theorems found in the literature and to develop machinery ...

Definable coaisles over rings of weak global dimension at most one [PDF]

open access: yesPublicacions matemàtiques, 2019
In the setting of the unbounded derived category D(R) of a ring R of weak global dimension at most one we consider t-structures with a definable coaisle.

Finiteness in derived categories of local rings [PDF]

open access: yes, 2005
New homotopy invariant finiteness conditions on modules over commutative rings are introduced, and their properties are studied systematically. A number of finiteness results for classical homological invariants like flat dimension, injective dimension ...

Homological invariants associated to semi-dualizing bimodules [PDF]

open access: yes, 2005
Cohen-Macaulay dimension for modules over a commutative noetherian local ring has been defined by A. A. Gerko. That is a homological invariant sharing many properties with projective dimension and Gorenstein dimension.
