• SOME RESULTS ON ONE MODULO THREE HARMONIC MEAN GRAPHS
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.
