摘要
A b-coloring of graph.. is a proper k-coloring C that verifies the following property: for every color class c(i), 1 <= i <= k, there exists a vertex x(i), with color c(i), such that all the other colors in C are utilized in x(i) neighbors. The b-chromatic number of a graph G, denoted by phi(G), is the largest integer k such that G may have a b-coloring by k colors. In this paper we discuss the b-coloring of prism graph Y-n, central graph of prism graph C(Y-n), middle graph of prism graph M(Y-n) and the total graph of prism graph T(Y-n) and we obtain the b-chromatic number for these graphs.
