Deterministic Distributed Edge-Coloring via Hypergraph Maximal Matching [PDF]
We present a deterministic distributed algorithm that computes a (2δ-1)-edge-coloring, or even list-edge-coloring, in any n-node graph with maximum degree δ, in O(log^8 δ ⋅ log n) rounds.

Majority Edge-Colorings of Graphs
We propose the notion of a majority $k$-edge-coloring of a graph $G$, which is an edge-coloring of $G$ with $k$ colors such that, for every vertex $u$ of $G$, at most half the edges of $G$ incident with $u$ have the same color. We show the best possible results that every graph of minimum degree at least $2$ has a majority $4$-edge-coloring, and that ...

On the Star Chromatic Index of Generalized Petersen Graphs
The star k-edge-coloring of graph G is a proper edge coloring using k colors such that no path or cycle of length four is bichromatic. The minimum number k for which G admits a star k-edge-coloring is called the star chromatic index of G, denoted by χ′s (

Some Equal Degree Graph Edge Chromatic Number
Let G(V, E) be a simple graph and k is a positive integer, if it exists a mapping of f, and satisfied with f(e1)≠6 = f(e2) for two incident edges e1,e2∉E(G), f(e1)≠6=f(e2), then f is called the k-proper-edge coloring of G(k-PEC for short).

Normal 5-edge-colorings of a family of Loupekhine snarks
In a proper edge-coloring of a cubic graph an edge uv is called poor or rich, if the set of colors of the edges incident to u and v contains exactly three or five colors, respectively.

M_{2}-edge colorings of dense graphs [PDF]
An edge coloring \(\varphi\) of a graph \(G\) is called an \(\mathrm{M}_i\)-edge coloring if \(|\varphi(v)|\leq i\) for every vertex \(v\) of \(G\), where \(\varphi(v)\) is the set of colors of edges incident with \(v\).

The strong edge-coloring for graphs with small edge weight
A strong edge-coloring of a graph G = ( V , E ) is a partition of its edge set E into induced matchings. The edge weight of a graph G is defined to be max { d G ( u ) + d G ( v ) | e = u v ∈ E ( G ) } . We study graphs with edge weight at most 7. We show

The Complexity of Distributed Edge Coloring with Small Palettes [PDF]
The complexity of distributed edge coloring depends heavily on the palette size as a function of the maximum degree $\Delta$. In this paper we explore the complexity of edge coloring in the LOCAL model in different palette size regimes. 1.

Abstract A split graph is a graph whose vertex set admits a partition into a stable set and a clique. The chromatic indexes for some subsets of split graphs, such as split graphs with odd maximum degree and split-indifference graphs, are known. However, for the general class, the problem remains unsolved.

Complete edge-colored permutation graphs
Nous introduisons le concept de graphes de permutation complets de couleur d'arête comme des graphes complets qui sont l'union bord-disjonction de graphes de permutation « classiques ». Nous montrons qu'un graphe G=(V,E) est un graphe de permutation complet de couleur de bord si et seulement si chaque sous-graphe monochromatique de G est un graphe de ...
