On the decomposition of circulant graphs using algorithmic approaches

open access: yesAlexandria Engineering Journal, 2022
Many structural models in chemistry, biology, computer science, sociology, and operations research can be analyzed using graph theory. Some examples of these structure models are species movement between regions, molecular bonds, shortest spanning trees,

The minimal and maximal energies of all cubic circulant graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
In recent article, Zhou and Zhou conjectured that among cubic circulant graphs with n vertices the maximum energy occurs whenever the largest number of components is attained.

Circulant topologies dataset

open access: yes, 2022
Circulant topologies with different generators count (2-10). This is a dataset consisting of signatures of optimal circulant topologies for various parameters. Circulants are regular topologies based on the Cayley graphs of a cyclic group.

Integral mixed circulant graphs

open access: yesDiscrete Mathematics, 2023
A mixed graph is said to be \textit{integral} if all the eigenvalues of its Hermitian adjacency matrix are integer. The \textit{mixed circulant graph} $Circ(\mathbb{Z}_n,\mathcal{C})$ is a mixed graph on the vertex set $\mathbb{Z}_n$ and edge set $\{ (a,b): b-a\in \mathcal{C} \}$, where $0\not\in \mathcal{C}$.

Hyper-Hamiltonian circulants

open access: yesElectronic Journal of Graph Theory and Applications, 2021
A Hamiltonian graph G = (V,E) is called hyper-Hamiltonian if G-v is Hamiltonian for any v ∈ V(G). G is called a circulant if its automorphism group contains a |V(G)|-cycle.

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
