title: On the relation between W'/W index, hyper-Wiener index, and Wiener numbers
abstract: It is shown analytically that the W'/W index, the hyper-Wiener index, and the Wiener number are closely related graph-theoretical invariants for acyclic structures. A general analytical expression for the hyper-Wiener index of a tree is derived too.
