Frequency Assignment Model of Zero Divisor Graph
Journal of Applied Mathematics, 2021 Given a frequency assignment network model is a zero divisor graph Γ=V,E of commutative ring Rη, in this model, each node is considered to be a channel and their labelings are said to be the frequencies, which are assigned by the L2,1 and L3,2,1 labeling

On zero-divisors of semimodules and semialgebras [PDF]
Georgian Mathematical Journal, 2019 Abstract We prove McCoy’s property for the zero-divisors of polynomials in semirings, investigate the zero-divisors of semimodules and prove that under suitable conditions, the monoid semimodule M

Noncommutativity and noncentral zero divisors [PDF]
International Journal of Mathematics and Mathematical Sciences, 1999 Let R be a ring, Z its center, and D the set of zero divisors. For finite noncommutative rings, it is known that D\Z ≠ ∅. We investigate the size of |D\Z| in this case and, also, in the case of infinite noncommutative rings with D\Z ≠ ∅.

Modeling General Asymptotic Calabi–Yau Periods
Fortschritte 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 ...

The Zero Divisor Graph of the Ring Zqp.
Science Journal of University of Zakho, 2015 In this paper we construct a star zero divisor graph from the zero divisor graph of the ring Zqp. The star zero divisor graph is obtained by removing some vertices from the zero divisor graph Γ(Zqp), in different ways , but the best way to get star zero ...

Induced subgraphs of zero-divisor graphs
Discrete Mathematics, 2023 The zero-divisor graph of a finite commutative ring with unity is the graph whose vertex set is the set of zero-divisors in the ring, with $a$ and $b$ adjacent if $ab=0$. We show that the class of zero-divisor graphs is universal, in the sense that every finite graph is isomorphic to an induced subgraph of a zero-divisor graph.

Eulerian and pancyclic zero-divisor graphs of ordered sets
AKCE International Journal of Graphs and CombinatoricsIn 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 ...
