The Wiener index is a graph parameter originating from chemical graph theory. It is defined as the sum of the lengths of the shortest paths between all unordered pairs of vertices in a given graph. In 1991, Šoltés [12] posed the following problem regarding the Wiener index. Find all graphs such that its Wiener index is preserved upon removal of any vertex. The problem is far from being solved and to this day, only one graph with such property is known — the cycle graph on 11 vertices. In this…

On the Wiener Polarity Index
The Wiener polarity index WP (G) of a graph G is the number of unordered pairs of vertices {u, v} of G such that the distance of u and v is equal to 3. In this paper, we obtain the relation between
