Neighborhood vertex corona product of graphs in a semi-total point graph

This paper delves into an examination of various topological indices, encompassing the modified Albertson index, the initial Gourava index, the secondary Gourava index, the hyper initial Gourava index, the hyper secondary Gourava index, the third Zagreb index, redefined second Zagreb index, the Harmonic index, the Square F-index, the VL index, the Sombar index, and the Nirmala index. The focus is on their utility in the analysis of quantitative structure-activity relationships (QSAR) and quantitative structure-property relationships (QSPR). By leveraging the minimum and maximum degrees of the graph G, we establish lower bounds for these indices. These findings offer novel insights into the application of topological invariants in the realms of QSAR and QSPR.
