2- Dominator Coloring for Various Graphs in Graph Theory

A. Sangeetha Devi, M. M. Shanmugapriya

Abstract: Given a graph G, the dominator coloring problem seeks a proper coloring of G with the additional property that every vertex in the graphG dominates at least 2-color class. In this paper, as an extension of Dominator coloring such that various graph using 2-dominator coloring has been discussed.
