On the Adjacent Strong Equitable Edge Coloring of Pn ∨ Pn, Pn ∨ Cn and Cn ∨ Cn
MATEC Web of Conferences, 2016 A proper edge coloring of graph G is called equitable adjacent strong edge coloring if colored sets from every two adjacent vertices incident edge are different,and the number of edges in any two color classes differ by at most one,which the required ...

M_{2}-edge colorings of dense graphs [PDF]
Opuscula Mathematica, 2016 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 \(v\).

Vertex‐disjoint properly edge‐colored cycles in edge‐colored complete graphs [PDF]
Journal of Graph Theory, 2019 AbstractIt is conjectured that every edge‐colored complete graph on vertices satisfying contains vertex‐disjoint properly edge‐colored cycles. We confirm this conjecture for , prove several additional weaker results for general , and we establish structural properties of possible minimum counterexamples to the conjecture.

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.

Normal edge-colorings of cubic graphs [PDF]
, 2019 A normal $k$-edge-coloring of a cubic graph is an edge-coloring with $k$ colors having the additional property that when looking at the set of colors assigned to any edge $e$ and the four edges adjacent it, we have either exactly five distinct colors or ...

Edge Cover Through Edge Coloring
The Electronic Journal of CombinatoricsLet $G$ be a multigraph. A subset $F$ of $E(G)$ is an edge cover of $G$ if every vertex of $G$ is incident to an edge of $F$. The cover index, $\xi(G)$, is the largest number of edge covers into which the edges of $G$ can be partitioned. Clearly $\xi(G) \le \delta(G)$, the minimum degree of $G$.

Opuscula Mathematica, 2022 We explore four kinds of edge colorings defined by the requirement of equal number of colors appearing, in particular ways, around each vertex or each edge. We obtain the characterization of graphs colorable in such a way that the ends of each edge see (not regarding the edge color itself) \(q\) colors (resp.

Decompositions of Plane Graphs Under Parity Constrains Given by Faces
Discussiones Mathematicae Graph Theory, 2013 An edge coloring of a plane graph G is facially proper if no two faceadjacent edges of G receive the same color. A facial (facially proper) parity edge coloring of a plane graph G is an (facially proper) edge coloring with the property that, for each ...
