A note on a graph related to the comaximal ideal graph of a commutative ring
(Yazd University, 2017-02-01)The rings considered in this article are commutative with identity which admit at least two maximal ideals. This article is inspired by the work done on the comaximal ideal graph of a commutative ring. Let R ...

On two-dimensional Cayley graphs
(Yazd University, 2017-02-01)A subset W of the vertices of a graph G is a resolving set for G when for each pair of distinct vertices u,v in V (G) there exists w in W ...

The Main Eigenvalues of the Undirected Power Graph of a Group
(Yazd University, 2017-02-01)The undirected power graph of a finite group $G$, $P(G)$, is a graph with the group elements of $G$ as vertices and two vertices are adjacent if and only if one of them is a power of the other. Let $A$ be an adjacency ...

D-Spectrum and D-Energy of Complements of Iterated Line Graphs of Regular Graphs
(Yazd University, 2017-02-01)The D-eigenvalues {µ1,…,µp} of a graph G are the eigenvalues of its distance matrix D and form its D-spectrum. The D-energy, ED(G) of G is given by ED (G) =∑i=1 ...
