The r-dynamic edge coloring of a closed helm graph

As a natural generalization of the classical coloring problem in graph theory, the dynamic coloring problem deals with the existence of a proper coloring c of a graph so that |c(N(v))| ≥ min{r, d (v)} for every vertex v . In this paper, we obtain the r-dynamic edge chromatic number of any given clos...

Descripción
Sumario:As a natural generalization of the classical coloring problem in graph theory, the dynamic coloring problem deals with the existence of a proper coloring c of a graph so that |c(N(v))| ≥ min{r, d (v)} for every vertex v . In this paper, we obtain the r-dynamic edge chromatic number of any given closed helm graph for any positive integer r. This coincides with the r-dynamic chromatic number of the line graph of a closed helm graph.
