On the relation between W'/W index, Hyper-Wiener index and Wiener number

The hyper-Wiener index was recently introduced by Randić. It is shown analytically that the hyper-Wiener index, the Wiener number and the W'/W index are closely related graph-theoretical inveriants for acyclic structures. On the basis of this relationship the general analytical expression for the hyper-Wiener index of acyclic structures is derived. The formula provides an easy method to calculate the hyper-Wiener index for any connected acyclic graph.
