摘要
The Wiener index of a connected graph is the sum of the distances between all pairs of vertices in the graph. It was conjectured that theWiener index of an n-vertex maximal planar graph is at most left perpendicular1/18 (n(3) + 3n(2))right perpendicular. We prove this conjecture and determine the unique n-vertex maximal planar graph attaining this maximum, for every n >= 10.
