Mathematical aspects of Wiener index
Martin Knor, Riste Škrekovski, Aleksandra Tepeh · Ars Mathematica Contemporanea · 2016
The Wiener index (i.e., the total distance or the transmission number), defined as the sum of distances between all unordered pairs of vertices in a graph, is one of the most popular molecular descriptors. In this article we summarize some results, conjectures and problems on this molecular descriptor, with emphasis on works we were involved in.
