Sensitivity and Hamming Graphs

open access: yesJournal of Graph Theory, Volume 112, Issue 3, Page 296-305, July 2026.
ABSTRACT For any m ≥ 3 we show that the Hamming graph H ( n , m ) admits an imbalanced partition into 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‐ary Sensitivity Conjecture of Asensio, García‐Marco, and Knauer.

Colouring Cayley Graphs [PDF]

open access: yes, 2005
We will discuss three ways to bound the chromatic number on a Cayley graph. 1. If the connection set contains information about a smaller graph, then these two graphs are related.

Perfect state transfer in unitary Cayley graphs over local rings [PDF]

open access: yesTransactions on Combinatorics, 2014
In this work, using eigenvalues and eigenvectors of unitary Cayley graphs over finite local rings and elementary linear algebra, we characterize which local rings allowing PST occurring in its unitary Cayley graph.

Color Energy Of A Unitary Cayley Graph

open access: yesDiscussiones Mathematicae Graph Theory, 2014
Let G be a vertex colored graph. The minimum number χ(G) of colors needed for coloring of a graph G is called the chromatic number. Recently, Adiga et al.

On the Unitary Cayley Graph of a Ring [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2012
Let $R$ be a ring with identity. The unitary Cayley graph of a ring $R$, denoted by $G_{R}$, is the graph, whose vertex set is $R$, and in which $\{x,y\}$ is an edge if and only if $x-y$ is a unit of $R$. In this paper we find chromatic, clique and independence number of $G_{R}$, where $R$ is a finite ring.

Maximum Induced Trees and Forests of Bounded Degree in Random Graphs

open access: yesRandom Structures &Algorithms, Volume 68, Issue 4, July 2026.
ABSTRACT The asymptotic behavior of the maximum sizes of induced trees and forests has been studied extensively in the last few decades, though the overall picture is far from being complete. In this paper, we close several significant gaps: (1) We prove 2‐point concentration of the maximum sizes of an induced forest and an induced tree with maximum ...

Edge-Transitivity of Cayley Graphs Generated by Transpositions

open access: yesDiscussiones Mathematicae Graph Theory, 2016
Let S be a set of transpositions generating the symmetric group Sn (n ≥ 5). The transposition graph of S is defined to be the graph with vertex set {1, . . . , n}, and with vertices i and j being adjacent in T(S) whenever (i, j) ∈ S. In the present note,
