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 MrG, geometric arithmetic index GAG, harmonic index HG, general version of harmonic index HrG, sum connectivity index λG, general sum connectivity index λrG, forgotten topological index FG, and many more for the Robertson apex graph. Additionally, we calculated the newly developed topological indices such as the AG2G and Sanskruti index for the Robertson apex graph G.
