摘要
W-p(G) is Wiener polarity index of the graph G that is defined as the numeral of unordered pairs of vertices which are at distance three in G. W-p(G) is considered as one of the classic topological indices and its properties have been widely studied for numerous graphs in recent years. In the currnt article an exact formula for the Wiener polarity index of nanostar dendrimers is computed.
