Some Structural Properties of Unitary Addition Cayley Graphs

open access: yesInternational Journal of Computer Applications, 2015
For a positive integer n > 1, the unitary addition Cayley graph Gn is the graph whose vertex set is V (Gn) = Zn = f0;1;2; ;n 1g and the edge set E(Gn) =fabj a;b2 Zn;a + b2 Ung where Un =fa2 Zn j gcd(a;n) = 1g. For Gn the independence number, chromatic number, edge chromatic number, diameter, vertex connectivity, edge connectivity and perfectness are ...

Quadratic unitary Cayley graphs of finite commutative rings

open access: yesLinear Algebra and its Applications, 2015
The purpose of this paper is to study spectral properties of a family of Cayley graphs on finite commutative rings. Let $R$ be such a ring and $R^\times$ its set of units. Let $Q_R=\{u^2: u\in R^\times\}$ and $T_R=Q_R\cup(-Q_R)$. We define the quadratic unitary Cayley graph of $R$, denoted by $\mathcal{G}_R$, to be the Cayley graph on the additive ...

A COMPLETE CLASSIFICATION OF PERFECT UNITARY CAYLEY GRAPHS

open access: yes
Due to their elegant and simple nature, unitary Cayley graphs have been an active research topic in the literature. These graphs are naturally connected to several branches of mathematics, including number theory, finite algebra, representation theory, and graph theory. In this article, we study the perfectness property of these graphs. More precisely,

Walks on Unitary Cayley Graphs and Applications

open access: yes, 2012
In this paper, we determine an explicit formula for the number of walks in $X_n = \textsf{Cay}(\mathbb{Z}_n,\mathbb{U}_n)$, the unitary Cayley Graphs of order $n$, between any pair of its vertices. With this result, we give the number of representations of a fixed residue class $\bmod{}n$ as the sum of $k$ units of $\mathbb{Z}_n$.
