چکیده مقاله

Suppose G is a graph and x;y in V(G). The length of a shortest path connecting x and y is denoted by d(x;y). The sum of all distances between pair of vertices is called the Wiener index W(G) of G [1]. The modified Wiener index ˆW is a graph invariant related to distance and symmetry of the graph under consideration. This invariant is defiend as ... In this talk, we will report our recent results on this subject [2].
