Abstract

In this paper we introduced the concept of complementary super edge magic labeling and Complementary Super Edge Magic strength of a graph G.A graph G (V, E ) is said to be complementary super edge magic if there exist a bijection f:V U E → { 1, 2, …………p+q } such that p+q+1 - f(x) is constant. Such a labeling is called complementary super edge magic labeling with complementary super edge magic strength. In this paper for a graph G(V, E ) the complementary super edge magic labeling and minimum of all constants which is called complementary super edge magic strength of G is defined. In this paper, we investigate whether some families of graphs are complementary or not?

INTRODUCTION
A labeling of a graph G is an assignment of mathematical objects to vertices , edges, or both vertices and edges subject to certain conditions. Graph labeling have applications in coding theory, networking addressing, and in many other fields. In most applications the labels are positive ( or nonnegative ) integers .In 1963 , Sedlack introduced a new class of labeling called magic labeling for a graph G (V, E ) , which is defined as a bijection f from E to a set of positive integers such that

MAIN RESULTS
In this paper the complementary super edge magic labeling and csems of two well known graphs such as the generalized prism Cm × Pn and G T ( n, n, n-1, n, 2n-1) are obtained. Before giving our main results we give a necessary and sufficient conditions for some graphs to have complementary super edge magic labeling.

Thus f is a super edge-magic of G with constant 15n, G and complementary super edge-magic labeling f is defined as for odd j,

Thus f (G) is complementary super edge -magic labeling of f with magic constant 21n-6 i.e. csems =21n-6. With this paper, we hope that interest in super edge-magic. and complementary super edgemagic labeling will aroused among those who study graph labeling.
