Pentavalent arc-transitive Cayley graphs on Frobenius groups with soluble vertex stabilizer
Open Mathematics, 2019 A Cayley graph Γ is said to be arc-transitive if its full automorphism group AutΓ is transitive on the arc set of Γ. In this paper we give a characterization of pentavalent arc-transitive Cayley graphs on a class of Frobenius groups with soluble vertex ...

Congruences and Hoehnke Radicals on Graphs
Discussiones Mathematicae Graph Theory, 2020 We motivate, introduce, and study radicals on classes of graphs. This concept, and the theory which is developed, imitates the original notion of a Hoehnke radical in universal algebra using congruences.

On divisibility graph for simple Zassenhaus groups [PDF]
, 2014 The divisibility graph $D(G)$ for a finite group $G$ is a graph with vertex set $cs~(G)\setminus\{1\}$ where $cs~(G)$ is the set of conjugacy class sizes of $G$. Two vertices $a$ and $b$ are adjacent whenever $a$ divides $b$ or $b$ divides $a$.

On the Clean Graph of Commutative Artinian Rings
International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.For a commutative Artinian ring R with unity, the clean graph Cl(R) is a graph with vertices in the form of an ordered pair (e, u), where e is an idempotent and u is a unit of ring R, respectively. Two distinct vertices (e, u) and (f, v) are adjacent in Cl(R) if and only if ef = fe = 0 or uv = vu = 1.

The rigidity of a partially triangulated torus
Proceedings of the London Mathematical Society, Volume 118, Issue 5, Page 1277-1304, May 2019., 2019 Abstract A simple graph is 3‐rigid if its generic embeddings in R3 are infinitesimally rigid. Necessary and sufficient conditions are obtained for the minimal 3‐rigidity of a simple graph obtained from a triangulated torus by the deletion of edges interior to an embedded triangulated disc.

On 7-valent symmetric graphs of order 2pq and 11-valent symmetric graphs of order 4pq
Open Mathematics, 2022 A graph is said to be symmetric if its automorphism group is transitive on its arcs. This article is one of a series of articles devoted to characterizing prime-valent arc-transitive graphs of square-free order or twice square-free order. In this article,

Journal of Applied Mathematics, Volume 2025, Issue 1, 2025.This article explores numerous significant additive topological indices based on degrees for linear functional graphs over finite‐dimensional vector spaces. Specifically, we derive some unique topological indices, such as the eccentricity‐based indices and the Wiener index.
