Relations between Wiener, hyper-Wiener and some Zagreb type indices

Abstract

In this paper, some inequalities between the Wiener, hyper-Wiener, first Zagreb, second Zagreb, first reformulated Zagreb, second reformulated Zagreb and the general Zagreb indices of a simple graph are given. Our results improve some earlier bonds between these graph invariants.
