A method for computation of the multiplicative Wiener index of C 4 nanotubes and nanotori

Abstract

The multiplicative Wiener index, π (G) , is equal to the product of distances between all pairs of vertexes of a (molecular) graph G. In this paper we compute this index for some nanotubes and nanotori by consider them as cartesian product of paths and cycles. Also we compute this index for some composite graphs.
