Abstract

Abstract : A topological index, also known as connectivity index, is a molecular structure descriptor calculated from a molecular graph of a chemical compound which characterizes its topology. Various topological indices are categorized based on their degree, distance, and spectrum. In this study, we calculated and analyzed the degree-based topological indices such as first general Zagreb index M r G, geometric arithmetic index GA G, harmonic index H G, general version of harmonic index H r G, sum connectivity index λ G, general sum connectivity index λ r G, forgotten topological index F G, and many more for the Robertson apex graph. Additionally, we calculated the newly developed topological indices such as the AG 2 G and Sanskruti index for the Robertson apex graph G .
