PRIME LABELINGS OF SPLIT GRAPH OF SUNLET GRAPH

Abstract

        A graph  G = ( V, E )  with n vertices is said to admit prime labeling if its vertices can be labeled with distinct positive integers not exceed n such that the label   of each pair of adjacent vertices are relatively prime. A graph G which admits prime labeling is called a prime graph. In this paper, we investigate prime labeling for some classes of graph. In particular, we discuss on prime labeling of The Sunlet graph . When n is even (or) odd.
