A comparative study of sum-connectivity and product-connectivity Gourava indices for benzenoid hydrocarbons

Nagesh H. M, Vijaya Chandra Kumar U, Azghar Pasha B +1

This study evaluates the sum-connectivity ( $S GO$ ) and product-connectivity ( $P GO$ ) Gourava indices as molecular descriptors for benzenoid hydrocarbons. Using a dataset of 30 benzen…

A Comparative Study of Exponential Sum-Connectivity and Product-Connectivity Gourava Indices for Benzenoid Hydrocarbons

H. M. Nagesh, B. Azghar Pasha, U. Vijaya Chandra Kumar +1

In this work, the exponential sum-connectivity Gourava index ( $e^{S GO (G)}$ ) and the exponential product-connectivity Gourava index ( $e^{P GO (G)}$ ) are computed and comparatively ana…

Vertex energy distributions in regular graph structures

H. M. Nagesh, U. Vijaya Chandra Kumar, N. Narahari

The energy of a vertex $v_{i}$ in a graph $G$ is defined as $E_{G} (v_{i}) = ∣ A ∣_{ii}$ , where $A$ is the adjacency matrix of $G$ , $A^{*}$ denotes the conjugate transpose of $A$ , a…
