Zagreb indices and Zagreb energies of some chemical compounds

Abstract

Topological indices are the tools provided by the mathematician to the chemists through graph the theory. Topological index is the number with the property that for each graph G1 which is isomorphic G2 implies topological indices of G1 and G2 are equal. The energy concept was introduces by I Gutman in the year 1978. Zagreb energy has its own importance in the study of physic-chemical properties of chemical compound. That is often modeled by chemical compound. In this paper, we find first Zagreb index, second Zagreb index. Hyper Zagreb index, First multiple Zagreb index, Second multiple Zagreb index, First Zagreb energy, second Zagreb energy and Hyper Zagreb energy of some chemical compounds.
