Özet

Graph invariants are numerical values assigned to some molecular graph G(M) to characterize its topological properties. The second neighbourhood or a 2 -distance degree of any vertex v in a graph G(M) is the cardinality of its second neighbors. In this research article, we formulated some expressions for the leap Zagreb indices, leap hyper-indices and F - leap indices, depending on the second degree of a vertex, of a family of a molecular graph called Polycyclic Aromatic Hydrocarbons PAH(s).
