The Dataset for Optimal Circulant Topologies

open access: yesBig Data and Cognitive Computing, 2023
This article presents software for the synthesis of circulant graphs and the dataset obtained. An algorithm and new methods, which increase the speed of finding optimal circulant topologies, are proposed.

Removing Symmetry in Circulant Graphs and Point-Block Incidence Graphs

open access: yesMathematics, 2021
An automorphism of a graph is a mapping of the vertices onto themselves such that connections between respective edges are preserved. A vertex v in a graph G is fixed if it is mapped to itself under every automorphism of G. The fixing number of a graph G

The hyperbolicity constant of infinite circulant graphs

open access: yesOpen Mathematics, 2017
If X is a geodesic metric space and x1, x2, x3 ∈ X, a geodesic triangle T = {x1, x2, x3} is the union of the three geodesics [x1x2], [x2x3] and [x3x1] in X.

Resolvability in Subdivision of Circulant Networks Cn1,k

open access: yesDiscrete Dynamics in Nature and Society, 2020
Circulant networks form a very important and widely explored class of graphs due to their interesting and wide-range applications in networking, facility location problems, and their symmetric properties.

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, .

Eternal domination and clique covering

open access: yesElectronic Journal of Graph Theory and Applications, 2022
We study the relationship between the eternal domination number of a graph and its clique cove-ring number using both large-scale computation and analytic methods. In doing so, we answer two open questions of Klostermeyer and Mynhardt.

Layout of random circulant graphs [PDF]

open access: yesLinear Algebra and its Applications, 2018
A circulant graph H is defined on the set of vertices V=\left\{ 1,\ldots,n\right\} and edges E=\left\{ \left(i,j\right):\left|i-j\right|\equiv s\left(\textrm{mod}n\right),s\in S\right\} , where S\subseteq\left\{ 1,\ldots,\lceil\frac{n-1}{2}\rceil\right\} . A random circulant graph results from deleting edges of H with probability 1-p.

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 $n>1$.
