论文摘要
我们确定树在$ n $顶点上所有树上特征集和子树核心之间的距离最大化。还讨论了此距离的渐近性质。研究了用固定直径的$ n $顶点上的树木不同中心部分之间的距离的问题
We determine the tree which maximizes the distance between characteristic set and subtree core over all trees on $n$ vertices. The asymptotic nature of this distance is also discussed. The problem of extremizing the distance between different central parts of trees on $n$ vertices with fixed diameter is studied
