On Edge Coloring Bipartite Graphs [PDF]

open access: yesSIAM Journal on Computing, 1982
The present paper shows how to find a minimal edge coloring of a bipartite graph with E edges and V vertices in time $O(E\log V)$.

On Twin Edge Colorings of Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2014
A twin edge k-coloring of a graph G is a proper edge coloring of G with the elements of Zk so that the induced vertex coloring in which the color of a vertex v in G is the sum (in Zk) of the colors of the edges incident with v is a proper vertex coloring.

Maximum Edge-Colorings Of Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2016
An r-maximum k-edge-coloring of G is a k-edge-coloring of G having a property that for every vertex v of degree dG(v) = d, d ≥ r, the maximum color, that is present at vertex v, occurs at v exactly r times. The r-maximum index χr′(G)$\chi _r^\prime (G)$

Antipodal Edge-Colorings of Hypercubes

open access: yesDiscussiones Mathematicae Graph Theory, 2019
Two vertices of the k-dimensional hypercube Qkare antipodal if they differ in every coordinate. Edges uv and xy are antipodal if u is antipodal to x and v is antipodal to y.

Acyclic and star coloring parameters of fractal cubic networks [PDF]

open access: yesScientific Reports
Interconnection networks are more vital in telecommunications because of the significant raise in the demand for high-speed networks as a result of the widespread use of computers and the growth of the internet.

Introduction to dominated edge chromatic number of a graph [PDF]

open access: yesOpuscula Mathematica, 2021
We introduce and study the dominated edge coloring of a graph. A dominated edge coloring of a graph \(G\), is a proper edge coloring of \(G\) such that each color class is dominated by at least one edge of \(G\).

Local edge (a, d) –antimagic coloring on sunflower, umbrella graph and its application

open access: yesAlifmatika, 2023
Suppose a graph G = (V, E) is a simple, connected and finite graph with vertex set V(G) and an edge set E(G). The local edge antimagic coloring is a combination of local antimagic labelling and edge coloring.

Edge Coloring Of Complement Bipolar Fuzzy Graphs

open access: yesRatio Mathematica, 2023
: Graph coloring is one of the most important problems of combinatorial optimization. Many problems of practical interest can be modeled as coloring problems.

From Edge-Coloring to Strong Edge-Coloring [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2015
In this paper we study a generalization of both proper edge-coloring and strong edge-coloring: $k$-intersection edge-coloring, introduced by Muthu, Narayanan and Subramanian. In this coloring, the set $S(v)$ of colors used by edges incident to a vertex $v$ does not intersect $S(u)$ on more than $k$ colors when $u$ and $v$ are adjacent.
