• STAR ATTACHED ODD-EVEN GRACEFUL GRAPHS

Abstract

The Odd-Even graceful labeling of a graph G with q edges means that there is an injection f : V(G) to {1,3,5,…,2q+1}  such that, when each edge uv is , the  resulting edge labels  are {2,4,6,…,2q .A graph which admits an Odd-Even graceful labeling is called an Odd-Even graceful graph. In this paper, we prove that some graphs namely <: w>, (,), (), < ,> are Odd-Even graceful.
