Zagreb indices, Hyper Zagreb indices and Redefined Zagreb indices of conical graph

Abstract

A topological index of graph G is a numerical parameter related to G which char- acterizes its topology and is preserved under isomorphism of graphs. Properties of the chemical compounds and topological indices are correlated. In this paper, we compute some topological indices such as Zagreb indices, Hyper Zagreb indices and Redefined Zagreb indices of conical graphs G(m, n). Moreover we compute the correlation coefficients between them.
