摘要:
研究了4圈图的Randic’指数,得到4圈图中取得较大Randic’指数的图的必要结构特征,并以1个特殊4圈图的指数值为界,证明大多数4圈图的Randic’指数均小于这一临界值,进而给出前9大Randic’指数和相应的极图,扩充了已有结果.
Abstract:
The Randic’ indices of the tetracyclic graphs is studied,and the necessary structural features of the larger Randic’ indices are obtained.It has proved that the Randic’ indices of most tetracyclic graphs are less than that of a special tetracyclic graph of boundary value,and then show the first nine Randic’ indices and the corresponding pole diagram,which is the expansion of the existing results.
