The The Cayley Graph of Semi-Direct Product of finite Groups: Interrelationships and Construction

open access: yesJournal of Kufa for Mathematics and Computer
In this paper, we study Cayley graph of the semi-direct product of two finite groups where  is an odd prime numbe. Specifically, we endeavor to establish a comprehensive understanding of the Cayley graph by investigating the interrelationships among ...

Homomorphisms of binary Cayley graphs

open access: yes, 2015
A binary Cayley graph is a Cayley graph based on a binary group. In 1982, Payan proved that any non-bipartite binary Cayley graph must contain a generalized Mycielski graph of an odd-cycle, implying that such a graph cannot have chromatic number 3.

Distance-regular Cayley graphs with small valency

open access: yes, 2019
We consider the problem of which distance-regular graphs with small valency are Cayley graphs. We determine the distance-regular Cayley graphs with valency at most $4$, the Cayley graphs among the distance-regular graphs with known putative intersection ...

A classification of finite groups with integral bi-Cayley graphs [PDF]

open access: yesTransactions on Combinatorics, 2015
The bi-Cayley graph of a finite group G with respect to a subset S⊆G ‎, ‎which is denoted by \BCay(G,S) ‎, ‎is the graph with‎ ‎vertex set G×{1,2} and edge set {{(x,1)‎,‎(sx,2)}∣x∈G‎,‎ s∈S} ‎. ‎A‎ ‎finite group G is called a \textit{bi-Cayley integral

On the Finite Groups that all Their Semi-Cayley Graphs are Quasi-Abelian [PDF]

open access: yesMathematics Interdisciplinary Research, 2018
In this paper, we prove that every semi-Cayley graph over a group G is quasi-abelian if and only if G is abelian.

Intersection Numbers of the Natural Embedding of the Twisted Triality Hexagon T ( q 3 , q ) ${\mathsf{T}}({q}^{3},q)$ in PG ( 7 , q 3 ) ${\mathsf{PG}}(7,{q}^{3})$

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT In this paper, we study and characterise the natural embedding of the twisted triality hexagon T ( q 3 , q ) ${\mathsf{T}}({q}^{3},q)$ in PG ( 7 , q 3 ) ${\mathsf{PG}}(7,{q}^{3})$. We begin by describing the possible intersections of subspaces of PG ( 7 , q 3 ) ${\mathsf{PG}}(7,{q}^{3})$ with T ( q 3 , q ) ${\mathsf{T}}({q}^{3},q)$.

Certain Structural Properties for the Direct Product of Cayley Graphs and Their Theoretical Applications

open access: yesJournal of Mathematics
Symmetry properties are of vital importance for graphs. The famous Cayley graph is a good mathematical model as its high symmetry. The normality of the graph can well reflect the symmetry of the graph.

Quantum simulation of Cayley-tree Ising Hamiltonians with three-dimensional Rydberg atoms

open access: yesPhysical Review Research, 2021
Significant efforts are being directed toward developing a quantum simulator capable of solving combinatorial optimization problems. The challenges are Hamiltonian programming in terms of high-dimensional qubit connectivities and large-scale ...

Sensitivity and Hamming Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT For any m ≥ 3 $m\ge 3$ we show that the Hamming graph H ( n , m ) $H(n,m)$ admits an imbalanced partition into m $m$ sets, each inducing a subgraph of low maximum degree. This improves previous results by Tandya and by Potechin and Tsang, and disproves the Strong m $m$‐ary Sensitivity Conjecture of Asensio, García‐Marco, and Knauer.

Generalized Cayley graphs

open access: yesDiscrete Mathematics, 1992
The autors introduce the concept of generalized Cayley graph. The main result is that if \(X\) is a graph, \(B(X)\) its double covering then \(B(X)\) is a Cayley graph if and only if \(X\) is a generalized Cayley graph. Another result is that a generalized Cayley graph that is stable is a Cayley graph. Furthermore a construction is given of a family of
