ABSTRACT

Mean labeling of graphs was introduced by S.Somasundram and R.Ponraj8. S.Somasundram and S.S. Sandhya introduced Harmonic mean labeling of graphs10. Similar to their concept Contra Harmonic mean labeling of graphs are introduced6. This paper deals with the Contra Harmonic mean labeling on H-graphs. Super Contra Harmonic mean labeling on H-graphs are also discussed.

Keywords :Contra Harmonic mean graph, Super Contra Harmonic mean graph, H-graph.
