Edge-Wiener index is a new topological invariant which is used in the study of physicochemical properties of chemical compounds and is closely associated with the Wiener index-To investigate the related properties of a class of important polygon chains comprehensively
an explicit expression for the expected value of the Edge-Wiener indices of a class of random polygonal chains is given. For applications
the Polyphenyl chains which can achieve the maximum and minimum of the EdgeWiener indices is found. And some results that have been published in recent papers are revealed. Finally the asymptotic behaviour of EdgeWiener indices is also considered.
