摘要: 刻划2连通图在条件NC≥n-δ+1下的Pnm泛连通图性. 得到结果: 2连通n阶图G, 若NC≥n-δ+1, 则G是Pn6泛连通 图或G2: (Ks+Kh).

关键词: 泛连通图, 邻域并,

Abstract: Let Pnm-pathconnected denote the graph of eac h pair of vertices that has paths each order from m to n, the following result i s obtained: for a 2-connected graph of order n(n≥6), if NC≥n-δ+1, then G is Pn6-pathconnected graphs or G=G2: (Ks+Kh), the result has also improved some results by Faudree etal and Wei Bing, Zhu Yong-jun.

Key words: pathconnected graphs, neighborhood unions, paths
