Abstract

An adjacent vertex distinguishing edge-coloring of a graph G is a proper edge coloring of G such that any pair of adjacent vertices are incident to distinct sets of colors. The minimum number of colors required for an adjacent vertex distinguishing edge-coloring of G is denoted by χ′ a (G). Let $\mathop{\mathrm{mad}}(G)$ and Δ denote the maximum average degree and the maximum degree of a graph G, respectively. In this paper, we prove the following results: (1) If $\mathop{\mathrm{mad}}(G)
