On k-terminal Cut Problem of-graph and 3-terminal Cut Problem of (n,n+1)-graph

论文标题：图的k-终端割与（n，n+1）图的3-终端割问题研究

It is shown that every minimum geodetic set of a graph does not contain its cut-vertices, and if G is a block graph with n≥3 vertices and k≥1 cut-vertices,then g=n-k.

图的每个最小测地集都不包括它的割点，如果图G是一个有n≥3个顶点，k≥1个割点的块图，那么g=n-k。

Let α to be independence number of graph G, in 1984 Fan showed: Let G be a 2-connected graph of order n, for every pair vertices x,y of d=2, if max{d,d}≥n/2, then G is Hamiltonian.

1984年，Fan给出了著名的Fan定理：若2连通n阶图G的距离是2的任意两点x、y均有max{d，d}≥n/2，则G是哈密尔顿图。

So with the adjacency matrix that has n vertices of a directed graph n2 units needed to store the adjacency matrix; on n vertices have an undirected graph Zexu into upper triangle, and only ...

因此用邻接矩阵来表示一个具有n个顶点的有向图时需要n2个单位来存储邻接矩阵；对有n个顶点的无向图则需存入上三角形，故只。。。

In 1997, Lenhard Ng Michelle Schultz[1] gave the definition of k -ordered Hamilton graphs,namely, let G be a Hamiltonian graph of order n,and for a positive integer k with k ≤n, we say that G is k -ordered if for every sequence S : v1 , v2,Λ,vk of k distinct vertices, there exists a hamiltonian cycle C of G such that the vertices of S are encountered on C in the specified order.

年， Lenhard Ng Michelle Schultz[1]给出k-可序( k ？ordered)哈密尔顿图的定义，即设G是n阶哈密尔顿图，对于正整数k，称G 是k -可序图，如果对于任意给定的k 个互不相同的顶点的有序子集S =( v1 ，v2，Λvk)( 2≤k ≤n)，存在G中的哈密尔顿圈C 包含S 且不改变其中元素的顺序。2000 年，R.J。
