On the Category of Harish-Chandra Block Modules [PDF]
, 2023 If $\Gamma$ is a subalgebra of $A$, then an $A$-module is called a Harish-Chandra module if it is the direct sum of its generalized weight spaces with respect to $\Gamma$.

Generalized Cofinitely δ-Semiperfect Modules
Annals of the Alexandru Ioan Cuza University - Mathematics, 2013 Abstract Let R be a ring and M be a left R-module. M is called a cofinitely generalized (weak) δ-supplemented module or briey a δ-CGS-module (δ-CGWS-module) if every cofinite submodule of M has a generalized (weak) δ-supplement in M. In this paper, we give various properties of these modules. It is shown that (1) The class of cofinitely generalized

On the Category of Weakly Laskerian Cofinite Modules
, 2014 Let $R$ denote a commutative Noetherian (not necessarily local) ring and $I$ be an ideal of $R$. The main purpose of this note is to show that the category $\mathscr{WL}(R, I)_{\it cof}$ of $I$-cofinite weakly Laskerian $R$-modules forms an Abelian ...

, 2023 This is the first paper of a three-part series in which we develop a theory of conformal blocks for $C_2$-cofinite vertex operator algebras (VOAs) that are not necessarily rational.

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 ...

Cofinitely eg-Supplemented Modules
, 2020 Let M be an R-module. If every cofinite essential submodule of M has a g-supplement in M, then M is called a cofinitely essential g-supplemented (or briefly cofinitely eg-supplemented) module.

An extension of the Hartshorne theorem on the characterization of cofinite complexes (Researches on theory of isometries and preserver problems from a various point of view) [PDF]
, 2019 This report is the announcement of the result on the characterization of cofinite complexes (the first one is in the talk at the RIMS conferencet). Let A be a homomorphic image of a Gorenstein ring of finite Krull dimension, J an ideal of A, and N^{cdot}

Cofinite modules and local cohomology
, 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 ...

COFINITENESS AND COASSOCIATED PRIMES OF LOCAL COHOMOLOGY MODULES
, 2009 Let R be a noetherian ring, alpha an ideal of R such that dim R/alpha = 1 and M a finite R-module. We will study cofiniteness and some other properties of the local cohomology modules H-alpha(i)(M).

Rad-circle plus-Supplemented Modules and Cofinitely Rad-circle plus-Supplemented Modules
, 2012 A module M is called (cofinitely) Rad-circle plus-supplemented if every (cofinite) submodule of M has a Rad-supplement that is a direct summand of M.
