Atom-Bond Connectivity Index in Various Graphs

A topological index, furthermore identified by way of connective index, is a molecular construction descriptor intended from a molecular graph of a chemical composite, which symbolizes its topology. Different topological indices remain branded established on their degree, spectrum, and distance. Here we investigation on we designed and analyzed the degree oriented topological directories, such as atom-bond connectivity index. Further investigated the index in regular graph, complete graph, complete bipartite graph, union of graphs, and join of graphs are derived. Further explain the theorem by examples.
