Lattice modules having small cofinite irreducibles [PDF]
International Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 3, Page 161-166, 2001., 2001 We introduce the concept of small cofinite irreducibles in Noetherian lattice modules and obtain several characterizations of this property.

Complexity of operations on cofinite languages [PDF]
, 2010 International audienceWe study the worst case complexity of regular operation on cofinite languages (i.e., languages whose complement is finite) and provide algorithms to compute efficiently the resulting minimal ...

Hartshorne's question on cofinite complexes [PDF]
, 2022 Let $\mathfrak{a}$ be a proper ideal of a commutative noetherian ring $R$ and $d$ a positive integer. We answer Hartshorne's question on cofinite complexes completely in the cases $\mathrm{dim}R=d$ or $\mathrm{dim}R/\mathfrak{a}=d-1$ or $\mathrm{ara ...

Modules cofinite and weakly cofinite with respect to an ideal [PDF]
, 2018 The purpose of the present paper is to continue the study of modules cofinite and weakly cofinite with respect to an ideal [Formula: see text] of a Noetherian ring [Formula: see text].

Groups with cofinite Zariski topology and potential density
, 2023 Tkachenko and Yaschenko [33] characterized the abelian groups G such that all proper unconditionally closed subsets of G are finite, these are precisely the abelian groups G having cofinite Zariski topology (they proved that such a G is either almost ...

CHARACTERIZATION OF WEAKLY PRIME SUBMODULE [PDF]
, 2021 Let R is a commutative ring with identity and M is a unital R-module. El-bast and Smith (1988) have researched and introduced the multiplication module. Prime submodule has been studied by Ameri (2002). Then Atani and Farzalipour (2007) have extended the

Cofinite modules and local cohomology [PDF]
, 1997 We show that if M is a finitely generated module over a commutative Noetherian local ring R and I is a dimension one ideal of R (i.e., dimRI = 1), then the local cohomology modules HIi(M) are I-cofinite; that is, ExtRj(RI, HIi(M)) is finitely generated ...

On Modules Having Small Cofinite Irreducibles
, 1994 In this paper we obtain several new characterizations of modules having small cofinite irreducibles. One of these characterizations involves a metric topology defined on the submodule lattice.

On the Beurling algebras Aα+(𝔻)—derivations and extensions
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 32, Page 1679-1701, 2004., 2004 Based on a description of the squares of cofinite primary ideals of Aα+(𝔻), we prove the following results: for α ≥ 1, there exists a derivation from Aα+(𝔻) into a finite‐dimensional module such that this derivation is unbounded on every dense subalgebra; for m ∈ ℕ and α ∈ [m, m + 1), every finite‐dimensional extension of Aα+(𝔻) splits algebraically if
