C. David Raj, C. Jayasekaran*

Abstract


A graph G with p vertices and q edges is said to be an one modulo three harmonic mean graph if there is a function φ from the vertex set of G to with φ is one-one and φ induces a bijection φ from the edge set of G to {1, 4, …, 3q – 2}, where φ (e = uv) = or and the function φ is called as an one modulo three harmonic mean labeling of G. In this paper, we investicate one modulo three harmonic mean labeling of some graphs.


Keywords


One modulo three harmonic mean labeling, one modulo three harmonic mean graphs.
