摘要
证明了张玉忠、周厚春(1996)文中的一个猜想:设T为n个点的树,则T的几何反比度Rc(T)≤12(n+22-3),n≥3,且对于特殊情形,得到比猜想更好的结果,从而说明其猜想对于树是成立的.
In this paper, we have proved a Zhang Yuzhong and Zhou Houchun's conjecture in 1996: Let T be a tree with order n , then its randicR c(T)≤12(n+22-3), n≥3, in this special case, the better result is obtained, that is, the conjecture is correct for the tree.
