A generalization of r-submodules
(University of Guilan, 2025-01-01)Let $R$ be a commutative ring with identity $1\neq 0$ and $M$ a non-zero unital $R$-module. In this paper, we present the concept of fully $I$-submodules of $M$ such that $I$ is an ideal of $R$ which is a generalization ...

A graph associated with minimal ideals of a ring
(University of Guilan, 2025-01-01)In this paper, a new kind of graph is introduced and investigated. The minimal ideal graph for a ring $R$ with unity is an undirected graph whose vertex set contains all non-trivial ideals of $R$. We denote the graph ...

On the maximal subsemigroups and rank properties of certain semigroups of partial injective contractions of a finite chain
(University of Guilan, 2025-01-01)Denote $[n]$ to be a finite $n$ chain $\{1,2,\ldots,n\}$. Let $\mathcal{CI}_{n}$ be the semigroup of partial injective contractions on $[n]$. Denote $\mathcal{ODDP}_{n}, \mathcal{ODCI}_{n}$ and $\mathcal{OCI}_{n}$ ...

A new approach to isomorphism theorems in Hilbert algebras
(University of Guilan, 2025-01-01)In this paper, we embark on an in-depth exploration of the profound connections between congruences, ideals, and homomorphisms in Hilbert algebras. Our research unveils a groundbreaking theorem that seamlessly integrates ...

Perfect 3-colorings of the line graphs of the connected bicubic graphs of order at most 12
(University of Guilan, 2025-01-01)Let $G =(V_G , E_G)$ be a graph and let $I$ be a finite set of size $m\geq 1$. A mapping $T:V_G \rightarrow I$ is called a perfect $m$-coloring with a parameter matrix $A = (a_{ij})_{i,j\in I }$ of $G$ if it ...

Order sum signed graph of a group
(University of Guilan, 2025-01-01)The order sum graph associated with the group $G$, denoted by $\Gamma_{os}$, is a graph with vertex set consisting of elements of $G$ and two vertices say $a$,$b$ $\in \Gamma_{os}$ are adjacent if $o(a)+o(b)>o(G)$, where ...

Neutrosophic primary submodule, localization and residual quotients
(University of Guilan, 2025-01-01)Let $R$ be a commutative ring with identity, $M$ be a unital $R$-module and let $L$ be a complete Heyting algebra. In this paper, among results on colon structures of $L$-neutrosophic submodules and $L$-neutrosophic ideals, ...

Derivations mapping into the Jacobson radical of a Banach algebra
(University of Guilan, 2025-01-01)Let $\mathcal{A}$ be a Banach algebra with Jacobson radical $Rad_{\mathcal{A}}$ and $d$ a continuous derivation of $\mathcal{A}$. The purpose of this article is to investigate some sufficient conditions under which ...

Two notes on “On the maximal spectrum of a module and Zariski topology”
(University of Guilan, 2025-01-01)For unitary modules over commutative rings with non-zero identity, Question 3.28 in [Bull. Malays. Math. Sci. Soc. 38(1) (2015) 303] asks if the maximal spectrum of a max-injective module is a max-spectral topological space ...

On the semitotal dominating sets of graphs
(University of Guilan, 2025-01-01)A set $D$ of vertices in an isolate-free graph $G$ is a semitotal dominating set of $G$ if $D$ is a dominating set of $G$ and every vertex in $D$ is within distance $2$ from another vertex of $D$.The semitotal domination ...

On almost radical ideals of noncommutative rings
(University of Guilan, 2025-01-01)Let J(R) denote the Jacobson radical of a commutative ring. In Khashan the notion of a J-ideal was introduced and studied. In khashanandece Khashan et al. introduced the concept of weakly J-ideals as a new generalization ...

Strongly Ψ -2-absorbing second submodules
(University of Guilan, 2025-01-01)Let R be a commutative ring with identity and M be an R-module.Let Ψ : S(M) →S(M) ∪ ∅ be a function, where S(M) denotes the set ofall submodules of M. The main purpose of this paper is to introduce andinvestigate the notion ...

Fuzzy GE-filters of GE-algebras
(University of Guilan, 2025-01-01)In this paper, notions of ∈t-set and Qt-set of a fuzzy set f in aGE-algebra X are introduced and defined fuzzy GE-algebra in terms of ∈t-set. We provided conditions for the ∈t-set and Qt-set of a fuzzy set f to be ...
