HARMONIC MEAN LABELLING OF SUBDIVISION AND SOME SPECIAL GRAPHS

Abstract

A chart G = (V, E) with p vertices and q edges is supposed to be a Harmonic mean diagram in the event that it is feasible to name the vertices xƐv with particular marks f(x) from 1,2,…. q+1 so that when each edge e =uv is named with the edge names are unmistakable. For this situation f is called Harmonic mean marking of G. In this paper we demonstrate the Harmonic mean naming conduct for some extraordinary diagrams.
