Finite injective dimension over rings with Noetherian cohomology [PDF]

open access: yes, 2011
We study rings which have Noetherian cohomology under the action of a ring of cohomology operators. The main result is a criterion for a complex of modules over such a ring to have finite injective dimension.

Factorizations of Elements in Noncommutative Rings: A Survey [PDF]

open access: yes, 2016
We survey results on factorizations of non zero-divisors into atoms (irreducible elements) in noncommutative rings. The point of view in this survey is motivated by the commutative theory of non-unique factorizations.

Class and rank of differential modules [PDF]

open access: yes, 2006
A differential module is a module equipped with a square-zero endomorphism. This structure underpins complexes of modules over rings, as well as differential graded modules over graded rings.

Specialization orders on atom spectra of Grothendieck categories [PDF]

open access: yes, 2015
We introduce systematic methods to construct Grothendieck categories from colored quivers and develop a theory of the specialization orders on the atom spectra of Grothendieck categories.

Noetherian properties of Fargues-Fontaine curves [PDF]

open access: yes, 2015
We establish that the extended Robba rings associated to a perfect nonarchimedean field of characteristic p, which arise in p-adic Hodge theory as certain completed localizations of the ring of Witt vectors, are strongly noetherian Banach rings; that is,

Noetherian local rings with Buchsbaum associated graded rings

open access: yesJournal of Algebra, 1984
Soient A un anneau local noethérien d'idéal maximal m et \(d=\dim A\), \(K=A/m\). On dit que A est un anneau de Buchsbaum si pour tout idéal q engendré par un système de paramètres de A la différence \(I(A)=\ell_ A(A/q)-e_ A(q)\) ne dépend pas de q, où \(\ell_ A(A/q)\) est la longueur du A-module A/q et \(e_ A(q)\) est la multiplicité de A relativement

A remark on the Riemann-Roch formula on affine schemes associated with Noetherian local rings

open access: yesTohoku Mathematical Journal, 1996
Let \(A\) be a homomorphic image of a regular local ring and \(r= \dim A\). Let \(A_*(Z)_{\mathbb{Q}}= \bigoplus_{i=0}^rA_i(Z)_{\mathbb{Q}}\) be the Chow group of the affine scheme \(Z= \text{Spec}(A)\) with rational coefficients and \(K_0(Z)\) the Grothendieck group of finitely generated \(A\)-modules.

Counting submodules of a module over a noetherian commutative ring

open access: yes, 2019
We count the number of submodules of an arbitrary module over a countable noetherian commutative ring. We give, along the way, a structural description of meager modules, which are defined as those that do not have the square of a simple module as ...

Some remarks on Mathieu subspaces over associative algebras

open access: yes, 2016
In this paper, we generalize some of the results of [9], and add some new results. Furthermore, we take a closer look at strongly simple algebras, which are introduced in [9].Comment: 27 pages; result numbers in section 2 and the end of section 3 have ...

Constructing modules with prescribed cohomological support [PDF]

open access: yes, 2007
A cohomological support, Supp_A(M), is defined for finitely generated modules M over an left noetherian ring R, with respect to a ring A of central cohomology operations on the derived category of R-modules.
