The locating chromatic number was introduced by Chartrand in 2002. Let G = (V, E) be a connected graph and let c be a coloring of G. If distinct vertices in G have distinct color codes, then c is called the locating coloring of G. The locating chromatic number of a graph, denoted as χL(G), is the minimum number of colors in a locating coloring of G. There have been several studies about the locating chromatic number of certain graphs. In this paper, we discuss the locating chromatic number of palm graph CkPlSm with k ≥ 3, l ≥ 2, m ≥ 2. © (2024), (International Association of Engineers). All rights reserved.
