Eulerian and pancyclic zero-divisor graphs of ordered sets

open access: yesAKCE International Journal of Graphs and Combinatorics
In this paper, we determine when the zero-divisor graph of a special class of a finite pseudocomplemented poset is Eulerian. Also, we deal with Hamiltonian, vertex pancyclic, and edge pancyclic properties of the complement of a zero-divisor graph of ...

The diameter of a zero divisor graph

open access: yesJournal of Algebra, 2006
AbstractLet R be a commutative ring and let Z(R)∗ be its set of nonzero zero divisors. The set Z(R)∗ makes up the vertices of the corresponding zero divisor graph, Γ(R), with two distinct vertices forming an edge if the product of the two elements is zero.

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 ...

Strong External Difference Families and Classification of α $\alpha $‐Valuations

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT One method of constructing (a2+1,2,a,1) $({a}^{2}+1,2,a,1)$‐SEDFs (i.e., strong external difference families) in Za2+1 ${{\mathbb{Z}}}_{{a}^{2}+1}$ makes use of α $\alpha $‐valuations of complete bipartite graphs Ka,a ${K}_{a,a}$. We explore this approach and we provide a classification theorem which shows that all such α $\alpha $‐valuations ...

Fault-tolerant metric dimension of zero-divisor graphs of commutative rings

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
Let R be a commutative ring with identity. The zero-divisor graph of R denoted by is an undirected graph where is the set of non-zero zero-divisors of R and there is an edge between the vertices z1 and z2 in if A set of vertices S resolves a graph G if ...

Some results on the total zero-divisor graph of a commutative ring

open access: yesArab Journal of Mathematical Sciences
PurposeThe purpose of this paper is to characterize a commutative ring R with identity which is not an integral domain such that ZT(R), the total zero-divisor graph of R is connected and to determine the diameter and radius of ZT(R) whenever ZT(R) is ...

Modeling General Asymptotic Calabi–Yau Periods

open access: yesFortschritte der Physik, EarlyView.
Abstract In the quest to uncovering the fundamental structures that underlie some of the asymptotic Swampland conjectures the authors initiate the general study of asymptotic period vectors of Calabi–Yau manifolds. The strategy is to exploit the constraints imposed by completeness, symmetry, and positivity, which are formalized in asymptotic Hodge ...

Note on Ideal Based Zero-Divisor Graph of a Commutative Ring

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2017
In this paper, we consider the ideal based zero divisor graph ΓI(R) of a commutative ring R. We discuss some graph theoretical properties of ΓI(R) in relation with zero divisor graph.

Computing Wiener and Hyper-Wiener Indices of Zero-Divisor Graph of ℤℊ3×ℤI1I2

open access: yesJournal of Function Spaces, 2022
Let S=ℤℊ3×ℤI1I2 be a commutative ring where ℊ,I1 and I2 are positive prime integers with I1≠I2. The zero-divisor graph assigned to S is an undirected graph, denoted as YS with vertex set V(Y(S)) consisting of all Zero-divisor of the ring S and for any c,
