On certain aspects of topological indices
Summary: 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 \(\text{GA} (G)\), harmonic index \(H(G)\), general version of harmonic index \(H_r (G)\), sum connectivity index \(\lambda (G)\), general sum connectivity index \(\lambda_r (G)\), forgotten topological index \(F(G)\), and many more for the Robertson apex graph. Additionally, we calculated the newly developed topological indices such as the \(\text{AG}_2(G)\) and Sanskruti index for the Robertson apex graph \(G\).
