Article Description

Abstract: A D(2)-vertex-distinguishing total coloring of a graph G is a proper total coloring such that no pair of vertices, within distance two, has the same set of colors, and the minimum number of colors required for such a coloring is called D(2)-vertex-distinguishing total chromatic number of G, and denoted by (Formula presented.). In this paper, we prove that (Formula presented.) for any graph G with Δ = 3.
