NEW MAJORIZATION FOR BOUNDED LINEAR OPERATORS IN HILBERT SPACES
Volume 11, Issue 2 , January 2024, Pages 1-12
Abstract
This work aims to introduce and investigate a preordering in $B(\mathcal{H}),$ the Banach space of all bounded linear operators defined on a complex Hilbert space $\mathcal{H}.$ It is called strong majorization and denoted by $S\prec_{s}T,$ for $S,T\in B(\mathcal{H}).$ ...

Volume 11, Issue 2 , January 2024, Pages 13-32
Abstract
In this paper, we introduce and study isotonic closure functions on a locale. These are pairs of the form $(L, \underline{{\mathrm{cl}}}_L)$, where$L$ is a locale and $\underline{{\mathrm{cl}}}_L\colon \mathcal{S}\!\ell(L) \rightarrow \mathcal{S}\!\ell(L)$is an isotonic closure function on the sublocales ...

Volume 11, Issue 2 , January 2024, Pages 33-51
Abstract
The main purpose of this article is to present a new approach to the classification of all indecomposable absorbing prime multiplication modules with finite-dimensional top over pullback rings of two Dedekind domains. First, ... Read MoreA KIND OF GRAPH STRUCTURE ASSOCIATED WITH ZERO-DIVISORS OF MONOID RINGS
Volume 11, Issue 2 , January 2024, Pages 53-63
Abstract
Let $R$ be an associative ring and $M$ be a monoid. In this paper, we introduce new kind of graph structure asociated with zero-divisors of monoid ring $R[M]$, calling it the $M$-Armendariz graph of a ring $R$ and denoted by $A(R,M)$. It is an undirected graph ... Read MoreQUOTIENT STRUCTURES IN EQUALITY ALGEBRAS
Volume 11, Issue 2 , January 2024, Pages 65-82
Abstract
The notion of fuzzy ideal in bounded equality algebras is defined, and several properties are studied. Fuzzy ideal generated by a fuzzy set is established, and a fuzzy ideal is made by using the collection of ideals. Characterizations of fuzzy ideal are discussed. Conditions for a fuzzy ideal to attains ... Read MoreA CLASSIFICATION OF EXTENSIONS GENERATED BY A ROOT OF AN EISENSTEIN-DUMAS POLYNOMIAL
Volume 11, Issue 2 , January 2024, Pages 83-91
Abstract
It is known that for a discrete valuation v of a field K with value group Z, an valued extension field (K′, v′) of (K, v) is generated by a root of an Eisenstein polynomial with respect to v having coefficients in K if and only if the extension (K′, v′)/(K, v) is totally ramified. ... Read MoreSOME PROPERTIES OF SUPER-GRAPH OF (G (R))^c AND ITS LINE GRAPH
Volume 11, Issue 2 , January 2024, Pages 93-112
Abstract
Let R be a commutative ring with identity 1≠0. The comaximal ideal graph of R is the simple, undirected graph whose vertex set is the set of all proper ideals of the ring R not contained in Jacobson radical of R and two vertices I and J are adjacent in this graph if and only if I+J=R. In this article, ... Read MoreEXTENSION AND TORSION FUNCTORS WITH RESPECT TO SERRE CLASSES
Volume 11, Issue 2 , January 2024, Pages 113-123
Abstract
In this paper we generalize the Rigidity Theorem and Zero Divisor Conjecture for an arbitrary Serre subcategory of modules. For this purpose, for any regularM-sequence x1; :::; xn with respect to S we prove that if TorR 2 ((x1;:::;x R n); M) 2 S, thenTorR i ((x1;:::;x R n); M) 2 S, for all i ≥ 1. ...

Volume 11, Issue 2 , January 2024, Pages 125-136
Abstract
In this paper, we introduce the concept of uniformly $n$-ideal ofcommutative rings which is a special type of $n$-ideal. We call aproper ideal $I$ of $R$ a uniformly $n$-ideal if there exists apositive integer $k$ for $a,b\in R$ whenever $ab\in I$ and$a\notin I$ implies that $b^{k}=0.$ The basic properties ...

Volume 11, Issue 2 , January 2024, Pages 137-145
Abstract
Let R be a commutative Noetherian ring, I, J be ideals of R such thatJ ⊆ I, and M be a finitely generated R-module. In this paper, we prove that theinvariants AJI(M) := inf{i ∈ N0 | JtHiI (M) is not Artinian for all t ∈ N0} and inf{i ∈N0 | JtHiI (M) is not minimax for all t ∈ ...

Volume 11, Issue 2 , January 2024, Pages 147-153
Abstract
Let $S=K[x_1,\ldots,x_n]$ be a polynomial ring over a field $K$ and$I\subset S$ be a monomial ideal with a linearresolution. Let$\frak{m}=(x_1,\ldots,x_n)$ be the unique homogeneous maximal ideal and $I\frak{m}$ be apolymatroidal ideal. We prove that if either $I\frak{m}$ is polymatroidal with strongexchange ...
