Local Distance Antimagic Labeling of Neighborhood Balanced Graphs

Abstract

Let G = (V, E) be a graph of order n without isolated vertices. A bijection f from vertex set of G to the set of integers from 1 to n is called a local distance antimagic labeling, if w(u) is not equal to w(v) for every edge uv of G, where w(u) is sum of labels of vertices adjacent to u. The local distance antimagic chromatic number xld(G) is defined to be the minimum number of colors taken over all colorings of G induced by local distance antimagic labelings of G. In this article, we study the local distance antimagic labeling of neighborhood balanced colored graphs.
