Abstract
A radio Dd-distance in harmonic mean labelling of a connected graph G is an injective map f from the vertex set V(G) to the N such that for two distinct vertices u and v of G, DDd(u,v)+[2f(u)f(v)/f(u)+f(v)]≥diamDd(G)+1. where DDd(u,v) denote Dd-distance between u and v diamDd(G) denotes the diameter of G. The radio Dd-distance in harmonic mean number of f, rhDdn(f) is the maximum label assigned to any vertex of G. The radio Dd-distance in harmonic mean number of G, rhDdn(G) is the minimum value of G. In the paper we find the radio Dd-distance in harmonic mean number of some standard graphs.
