Some graph operations on sum divisor cordial labeling related to H- graph

Abstract

A sum divisor cordial labeling of a graph with vertex set is a bijection such that each edge uv assigned the label 1 if 2 divides and 0 otherwise. Further, the number of edges labeled with 0 and the number of edges labeled with 1 differ by at most 1. A graph with a sum divisor cordial labeling is called a sum divisor cordial graph. In this paper, we prove that graphs ( is even), duplication of all edges of - graph ( is even),,, are sum divisor cordial graphs.
