Extensions of Vizing fans and Vizing's Theorem in graph edge coloring [PDF]

open access: yes, 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 ...

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.

Coloring Delaunay-edges and their generalizations [PDF]

open access: yesComputational Geometry, 2021
We consider geometric hypergraphs whose vertex set is a finite set of points (e.g., in the plane), and whose hyperedges are the intersections of this set with a family of geometric regions (e.g., axis-parallel rectangles). A typical coloring problem for such geometric hypergraphs asks, given an integer $k$, for the existence of an integer $m=m(k ...

Neighbor Distinguishing Colorings of Graphs with the Restriction for Maximum Average Degree

open access: yesAxioms, 2023
Neighbor distinguishing colorings of graphs represent powerful tools for solving the channel assignment problem in wireless communication networks. They consist of two forms of coloring: neighbor distinguishing edge coloring, and neighbor distinguishing ...

On Colorful Edge Triples in Edge-Colored Complete Graphs [PDF]

open access: yesGraphs and Combinatorics, 2020
AbstractAn edge-coloring of the complete graph $$K_n$$ K n we call F-caring if it leaves no F-subgraph of $$K_n$$ K n monochromatic and at the same time every subset of |V(F)| vertices contains in it at least one completely multicolored version of F. For the first two meaningful cases, when $$F=K_{1,3}$$ F = K 1 , 3 and $$F=P_4$$ F = P 4

Restrained star edge coloring of graphs and its application in optimal & safe storage practices

open access: yesRatio Mathematica, 2023
In this paper we introduce the concept of restrained star edge coloring of graphs by restraining the conditions of the star coloring of graphs. The restrained star edge coloring of graphs is a path based graph coloring which is said to be proper if all ...

Vertex-Coloring Edge-Weighting of Bipartite Graphs with Two Edge Weights [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
Let $G$ be a graph and $\mathcal{S}$ be a subset of $Z$. A vertex-coloring $\mathcal{S}$-edge-weighting of $G$ is an assignment of weights by the elements of $\mathcal{S}$ to each edge of $G$ so that adjacent vertices have different sums of incident ...

Planar graphs with $\Delta \geq 7$ and no triangle adjacent to a $C_4$ are minimally edge and total choosable [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
For planar graphs, we consider the problems of list edge coloring and list total coloring. Edge coloring is the problem of coloring the edges while ensuring that two edges that are adjacent receive different colors.

Community detection with colored edges [PDF]

open access: yes2016 IEEE International Symposium on Information Theory (ISIT), 2016
In this paper, we prove a sharp limit on the community detection problem with colored edges. We assume two equal-sized communities and there are $m$ different types of edges. If two vertices are in the same community, the distribution of edges follows $p_i=α_i\log{n}/n$ for $1\leq i \leq m$, otherwise the distribution of edges is $q_i=β_i\log{n}/n$ for
