Equitable Dominator Coloring of Line Graphs of Some Graphs

A proper vertex coloring of the graph G such that each vertex dominates at least one color class and the cardinalities of the color classes differ by at most 1 is called an equitable dominator coloring of G. The minimum number of colors used in this coloring is called the equitable dominator chromatic number (EDCN), represented by ₄₃ (G). This article explores the concept of equitable dominator coloring for the line graph L (G) of some graph classes.
