On Global Offensive Alliance in Zero-Divisor Graphs

open access: yesMathematics, 2022
Let Γ(V,E) be a simple connected graph with more than one vertex, without loops or multiple edges. A nonempty subset S⊆V is a global offensive alliance if every vertex v∈V−S satisfies that δS(v)≥δS¯(v)+1.

The Zero Divisor Graph of the Ring Z_(2^2 p)

open access: yesARO-The Scientific Journal of Koya University, 2016
In this paper, we consider the crossing number and the chromatic number of the zero divisor graph Γ(Z_(2^2 p)) to show that this type of zero divisor graphs is bipartite graph, and the smallest cycle in Γ(Z_(2^2 p)) is of length four this implies that ...

Boxicity of zero divisor graphs

open access: yesDiscrete Applied Mathematics
A $d$-dimensional box is the cartesian product $R_i\times\cdots\times R_d$ where each $R_i$ is a closed interval on the real line. The boxicity of a graph, denoted as $box(G)$, is the minimum integer $d\geq 0$ such that $G$ is the intersection graph of a collection of $d$-dimensional boxes.

COMPLEMENT OF THE ZERO DIVISOR GRAPH OF A LATTICE [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2013
AbstractIn this paper, we determine when $\mathop{({\Gamma }_{I} (L))}\nolimits ^{c} $, the complement of the zero divisor graph ${\Gamma }_{I} (L)$ with respect to a semiprime ideal $I$ of a lattice $L$, is connected and also determine its diameter, radius, centre and girth. Further, a form of Beck’s conjecture is proved for ${\Gamma }_{I} (L)$ when $\

Component graphs of vector spaces and zero-divisor graphs of ordered sets [PDF]

open access: yes, 2022
In this paper, nonzero component graphs and nonzero component union graphs of finite dimensional vector space are studied using the zero-divisor graph of specially constructed 0-1-distributive lattice and the zero-divisor graph of rings.

Line Graphs of Monogenic Semigroup Graphs

open access: yesJournal of Mathematics, 2021
The concept of monogenic semigroup graphs ΓSM is firstly introduced by Das et al. (2013) based on zero divisor graphs. In this study, we mainly discuss the some graph properties over the line graph LΓSM of ΓSM.

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).
