Strong Edge Coloring of Cayley Graphs and Some Product Graphs [PDF]

open access: yesGraphs and Combinatorics, 2022
AbstractA strong edge coloring of a graph G is a proper edge coloring of G such that every color class is an induced matching. The minimum number of colors required is termed the strong chromatic index. In this paper we determine the exact value of the strong chromatic index of all unitary Cayley graphs.

Upper Bounds for the Strong Chromatic Index of Halin Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2018
The strong chromatic index of a graph G, denoted by χ′s(G), is the minimum number of vertex induced matchings needed to partition the edge set of G. Let T be a tree without vertices of degree 2 and have at least one vertex of degree greater than 2.

Strong edge colorings of uniform graphs

open access: yesDiscrete Mathematics, 2004
A strong edge coloring of a graph is a (proper) edge coloring in which every color class is an induced matching. The strong chromatic index \(\chi_S(G)\) of a graph \(G\) is the minimum number of colors in a strong edge coloring of \(G\). For a bipartite graph \(G=(U\cup V, E)\), and for two nonempty sets \(U'\subseteq U\) and \(V'\subseteq V\), let ...

Strong edge-coloring of cubic bipartite graphs: A counterexample

open access: yesDiscrete Applied Mathematics, 2022
A strong edge-coloring $φ$ of a graph $G$ assigns colors to edges of $G$ such that $φ(e_1)\ne φ(e_2)$ whenever $e_1$ and $e_2$ are at distance no more than 1. It is equivalent to a proper vertex coloring of the square of the line graph of $G$. In 1990 Faudree, Schelp, Gyárfás, and Tuza conjectured that if $G$ is a bipartite graph with maximum degree 3 ...

Peacock Bundles: Bundle Coloring for Graphs with Globality-Locality Trade-off

open access: yes, 2016
Bundling of graph edges (node-to-node connections) is a common technique to enhance visibility of overall trends in the edge structure of a large graph layout, and a large variety of bundling algorithms have been proposed.

Coalition Resilient Outcomes in Max k-Cut Games

open access: yes, 2018
We investigate strong Nash equilibria in the \emph{max $k$-cut game}, where we are given an undirected edge-weighted graph together with a set $\{1,\ldots, k\}$ of $k$ colors. Nodes represent players and edges capture their mutual interests. The strategy

Adjacent strong edge coloring of graphs

open access: yesApplied Mathematics Letters, 2002
A proper edge coloring of a graph is an adjacent strong edge coloring if, for every adjacent vertices \(u\) and \(v\), the set of colors of all edges at \(u\) is different from the set of all colors of edges at \(v\). The authors determine the minimum number \(k\) such that a tree (a cycle, a complete graph) has an adjacent strong edge coloring with ...

Strong chromatic index of sparse graphs [PDF]

open access: yes, 2013
A coloring of the edges of a graph $G$ is strong if each color class is an induced matching of $G$. The strong chromatic index of $G$, denoted by $\chi_{s}^{\prime}(G)$, is the least number of colors in a strong edge coloring of $G$.
