On the Eigenvalue Spectrum of Cayley Graphs: Connections to Group Structure and Expander Properties

open access: yesMathematics
Cayley graphs sit at the intersection of algebra, geometry, and theoretical computer science. Their spectra encode fine structural information about both the underlying group and the graph itself.

On quasi-Cayley graphs

open access: yesDiscrete Applied Mathematics, 1997
Given a quasigroup \(Q\) with a right identity element and a right-associative generating subset \(S\), a quasi-Cayley graph \(\text{QC}(Q,S)\) is constructed in very much the same way as a Cayley graph is constructed from a given group and a symmetric generating set.

Identifiability of points and rigidity of hypergraphs under algebraic constraints

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract The identifiability problem arises naturally in a number of contexts in mathematics and computer science. Specific instances include local or global rigidity of graphs and unique completability of partially‐filled tensors subject to rank conditions.

A note on the k-degree Cayley graph [PDF]

open access: yes
The k-degree Cayley graph has been proposed by Hsieh and Hsiao (Networks 47 (2006), 26-36). They have shown that the k-degree Cayley graph is actually a Cayley graph.

Classification of 14-Valent 1-Regular Core-Free Cayley Graphs

open access: yesMathematics
A Cayley graph Σ=Cay(G,S) is called 1-regular core-free if G is core-free in some Y⩽AutΣ and AutΣ acts regularly on the set of 1-arcs of Σ. In this paper, we classify the 14-valent 1-regular core-free Cayley graphs.

L(2, 1)-Labeling of Circulant Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
An L(2, 1)-labeling of a graph Γ is an assignment of non-negative integers to the vertices such that adjacent vertices receive labels that differ by at least 2, and those at a distance of two receive labels that differ by at least one.

On the Foundational Arguments of Sufficient Dimension Reduction

open access: yesWIREs Computational Statistics, Volume 18, Issue 2, June 2026.
Contemporary Sufficient Dimension Reduction, a versatile method for extracting material information from data, can serve as a preprocessor for classical modeling and inference, or as a standalone theory that leads directly to statistical inference. ABSTRACT Sufficient dimension reduction (SDR) refers to supervised methods of dimension reduction that ...

Connectivity of addition Cayley graphs

open access: yesJournal of Combinatorial Theory, Series B, 2009
For any finite abelian group $G$ and any subset $S\seq G$, we determine the connectivity of the addition Cayley graph induced by $S$ on $G$. Moreover, we show that if this graph is not complete, then it possesses a minimum vertex cut of a special, explicitly described form.

Genus of total graphs from rings: A survey

open access: yesAKCE International Journal of Graphs and Combinatorics, 2018
Let R be a commutative ring. The total graph T Γ ( R ) of R is the undirected graph with vertex set R and two distinct vertices x and y are adjacent if x + y is a zero divisor in R . In this paper, we present a survey of results on the genus of T Γ ( R )
