Eccentric Harmonic Index for the Cartesian Product of Graphs

Eccentric Harmonic Index for the Cartesian Product of Graphs

Suppose ρ is a simple graph, then its eccentric harmonic index is defined as the sum of the terms 2/ea+eb for the edges vavb, where ea is the eccentricity of the ath vertex of the graph ρ. We symbolize the eccentric harmonic index (EHI) as He=Heρ. In this article, we determine He for the Cartesian p...
