Distributive lattices and some related topologies in comparison with zero-divisor graphs [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2021
In this paper,for a distributive lattice $\mathcal L$, we study and compare some lattice theoretic features of $\mathcal L$ and topological properties of the Stone spaces ${\rm Spec}(\mathcal L)$ and ${\rm Max}(\mathcal L)$ with the corresponding graph ...

A new additive function and the Smarandache divisor product sequences [PDF]

open access: yes, 2009
The main purpose of this paper is using the elementary method and the prime distribution theory to study the mean value properties of G(n) in Smarandache divisor product sequences fpd(n)g and fqd(n)g, and give two sharper asymptotic formulae for ...

Homology of Zero-Divisors

open access: yesRocky Mountain Journal of Mathematics, 2007
Let \(R\) be a commutative ring with unity. This paper studies \(Z(R)\) using homology group, where \(Z(R)\) is the set of zero-divisors in \(R\). In addition, the authors calculate the group \(H_{0}(R)\) in depth, in particular cases, and compute \(H_{1}(\frac{\mathbb{Z}}{p^{r}\mathbb{Z}})\) where \(p\) is a prime and \(r\geq 1\) is an integer.

On the eigenvalues of zero-divisor graph associated to finite commutative ring

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
Let Z(R) be the set of zero-divisors of a commutative ring R with non-zero identity and be the set of non-zero zero-divisors of R. The zero-divisor graph of R, denoted by is a simple graph whose vertex set is and two vertices are adjacent if and only if ...

On graphs with equal coprime index and clique number

open access: yesAKCE International Journal of Graphs and Combinatorics, 2023
Recently, Katre et al. introduced the concept of the coprime index of a graph. They asked to characterize the graphs for which the coprime index is the same as the clique number. In this paper, we partially solve this problem.

Classification of Genus Three Zero-Divisor Graphs

open access: yes, 2023
In this paper, we consider the problem of classifying commutative rings according to the genus number of its associating zero-divisor graphs. The zero-divisor graph of R, where R is a commutative ring with nonzero identity, denoted by Γ(R), is the ...

A class of zero divisor rings in which every graph is precisely the union of a complete graph and a complete bipartite graph

open access: yesOpen Mathematics, 2015
Recently, an interest is developed in estimating genus of the zero-divisor graph of a ring. In this note we investigate genera of graphs of a class of zero-divisor rings (a ring in which every element is a zero divisor).

Exploring the properties of the zero-divisor graph of direct product of $\ast$-rings [PDF]

open access: yesJournal of Mahani Mathematical Research
In this paper, we delve into the study of zero-divisor graphs in rings equipped with an involution. Specifically, we focus on abelian Rickart $\ast$-rings.
