Counting 2-circulant graphs [PDF]

open access: yesJournal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1985
AbstractAlspach and Sutcliffe call a graph X(S, q, F) 2-circulant if it consists of two isomorphic copies of circulant graphs X(p, S) and X(p, qS) on p vertices with “cross-edges” joining one another in a prescribed manner. In this paper, we enumerate the nonisomorphic classes of 2-circulant graphs X(S, q, F) such that |S| = m and |F| = k.

On the Metric Dimension of Directed and Undirected Circulant Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2020
The undirected circulant graph Cn(±1, ±2, . . . , ±t) consists of vertices v0, v1, . . . , vn−1 and undirected edges vivi+j, where 0 ≤ i ≤ n − 1, 1 ≤ j ≤ t (2 ≤ t ≤ n2{n \over 2} ), and the directed circulant graph Cn(1, t) consists of vertices v0, v1, .

Incidence and Laplacian matrices of wheel graphs and their inverses

open access: yesThe American Journal of Combinatorics, 2023
It has been an open problem to find the Moore-Penrose inverses of the incidence, Laplacian, and signless Laplacian matrices of families of graphs except trees and unicyclic graphs.

The eigenvalues and energy of integral circulant graphs [PDF]

open access: yesTransactions on Combinatorics, 2012
A graph is called textit{circulant} if it is a Cayley graph on acyclic group, i.e. its adjacency matrix is circulant. Let $D$ be aset of positive, proper divisors of the integer $n>1$.

On the Metric Index of Circulant Networks–An Algorithmic Approach

open access: yesIEEE Access, 2019
A vertex v of a graph G uniquely determines (resolves) a pair (v1, v2) of vertices of G if the distance between v and v1 is different from the distance between v and v2.

Structure and substructure connectivity of circulant graphs and hypercubes [PDF]

open access: yesArab Journal of Mathematical Sciences, 2021
Let H be a connected subgraph of a connected graph G. The H-structure connectivity of the graph G, denoted by κ(G;H), is the minimum cardinality of a minimal set of subgraphs F={H1′,H2′,…,Hm′} in G, such that every H′i∈F is isomorphic to H and removal of

Almost self-complementary circulant graphs

open access: yesDiscrete Mathematics, 2004
The concept of an {almost self-complementary graph} has been introduced by B. Alspach to get around the restriction that the order of a self-complementary regular graph must be odd. An {almost complement} of a graph \(\Gamma\) of even order is a graph obtained by removing the edges of a 1-factor from the complement of \( \Gamma \).
