Recent Studies on Some Graph Invariant

Topological indices are numerical parameters of a molecular graph which characterize bonding topology of a molecule and are necessarily structure invariant. The main aim behind the research of topological indices is to studying by a theoretical pathway, how to catch and convert the information encoded in the molecular structure in to one or more numbers - termed as topological indices, which is used to establish quantitative relationship between the structures and properties, biological activities and other experimental properties.
