Equitable Coloring on Corona Graph of Graphs

Abstract

The notion of equitable coloring was introduced by Meyer in 1973. This paper presents exact values of the equitable chromatic number of three corona graphs, which include the complete graph and its complement $K_m\circ \overline{K_n}$, the star graph and its complement $K_{1,m}\circ \overline{K_{1,n}}$, and the complete graph and complete graph $K_m\circ K_n$.
