A graph-theoretic approach to ring analysis: Dominant metric dimensions in zero-divisor graphs [PDF]

open access: yesHeliyon
This article investigates the concept of dominant metric dimensions in zero divisor graphs (ZD-graphs) associated with rings. Consider a finite commutative ring with unity, denoted as R, where nonzero elements x and y are identified as zero divisors if ...

Total perfect codes in graphs realized by commutative rings [PDF]

open access: yesTransactions on Combinatorics, 2022
Let $R$ be a commutative ring with unity not equal to zero and let $\Gamma(R)$ be a zero-divisor graph realized by $R$. For a simple, undirected, connected graph $G = (V, E)$, a {\it total perfect code} denoted by $C(G)$ in $G$ is a subset $C(G ...

The wiener index of the zero-divisor graph for a new class of residue class rings

open access: yesFrontiers in Chemistry, 2022
The zero-divisor graph of a commutative ring R, denoted by Γ(R), is a graph whose two distinct vertices x and y are joined by an edge if and only if xy = 0 or yx = 0.

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.

STRUCTURE OF ZERO-DIVISOR GRAPHS ASSOCIATED TO RING OF INTEGER MODULO n [PDF]

open access: yesJournal of Algebraic Systems, 2023
For a commutative ring $R$ with identity $1\neq 0$, let $Z^{*}(R)=Z(R)\setminus \lbrace 0\rbrace$ be the set of non-zero zero-divisors of $R$, where $Z(R)$ is the set of all zero-divisors of $R$.

Non Deterministic Zero Divisor Graph

open access: yesRatio Mathematica, 2023
A non-deterministic zero divisor graph refers to an element in a ring or algebraic structure that can multiply with another element to give zero, but the specific outcome of the multiplication is not uniquely determined.

Comments on the Clique Number of Zero-Divisor Graphs of Zn

open access: yesJournal of Mathematics, 2022
In 2008, J. Skowronek-kazio´w extended the study of the clique number ωGZn to the zero-divisor graph of the ring Zn, but their result was imperfect. In this paper, we reconsider ωGZn of the ring Zn and give some counterexamples. We propose a constructive
