Harmonic Zagreb-K-Banhatti Index of a Graph

V.R. Kulli

Abstract

The Zagreb indices and K-Banhatti indices are closely related. In this paper, we introduce the reformulated harmonic index, harmonic Zagreb-K-Banhatti index of a graph. We establish some bounds for the harmonic index and reformulated harmonic index. We also obtain lower and upper bounds for the harmonic Zagreb-K-Banhatti index of a graph in terms of Zagreb and K-Banhatti indices.

Keywords

harmonic index, reformulated harmonic index, harmonic Zagreb-K-Banhatti index, graph.
