Hyper-Wiener index and Laplacian spectrum

The hyper-Wiener index WWW of a chemical tree T is defined as the sum of the product n1 n2 n3, over all pairs u, u of vertices of T, where n1 and n2 are the number of vertices of T, lying on the two sides of the path which connects u and u, and n3 is the number of vertices lying between u and u.
