• GEOMETRIC MEAN LABELING ON DOUBLE TRIANGULAR SNAKES

Abstract

A Graph G = (V, E) with p vertices and q edges is called a Geometric mean graph if it is possible to label the vertices xÎV with distinct labels f(x) from 1, 2………q+1 in such a way that when each edge e=uv is labeled with f(e = vu) = or then the edge labels are distinct. In this case, f is called Geometric mean labeling of G. In this paper we prove that Double Triangle snake and Alternate Double Triangular snake graphs are Geometric mean graphs.
