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

On Twin Edge Colorings of Graphs
Discussiones 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
Discussiones 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)$\chi _r^\prime (G)$

Nonrepetitive edge-colorings of trees [PDF]
Discrete Mathematics & Theoretical Computer Science, 2017 A repetition is a sequence of symbols in which the first half is the same as the second half. An edge-coloring of a graph is repetition-free or nonrepetitive if there is no path with a color pattern that is a repetition.

Antipodal Edge-Colorings of Hypercubes
Discussiones 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.

On Weighted Bipartite Edge Coloring. [PDF]
, 2015 We study weighted bipartite edge coloring problem, which is a generalization of two classical problems: bin packing and edge coloring. This problem has been inspired from the study of Clos networks in multirate switching environment in communication networks.

Extensions of Vizing fans and Vizing's Theorem in graph edge coloring [PDF]
, 2022 Graph edge coloring is a well established subject in the field of graph theory. It is one of the basic combinatorial optimization problem: Color the edges of a graph $G$ with as few colors as possible such that each edge receives a color and adjacent ...

Majority Edge-Colorings of Graphs
The Electronic Journal of Combinatorics, 2023 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 ...
