1) 2n-pairs contractible graphs
2n-对可收缩图
1.
The relations between 2n-critical graphs,(2n+1)-contractible graphs,2n-pairs contractible graphs,and n-extendable graphs are investigated.
若G有完美匹配,且对于V(G)的任意2n个两两不相交的子集S_1,S_2,…,S_(2n),这里|S_1|=|S_2|=…=|S_(2n)|=2,图β_(2n)(G,S_1,S_2,…,S_(2n))有完美匹配,则称G是一个2n-对可收缩图。
2) unretractive graph
不可收缩图
1.
Graphs and their endomorphism semigroups are considered and the characterization of E-S unretractive graphs is given in this paper.
本文考虑了图及其自同态半群，给出了Ｅ—Ｓ不可收缩图的结构刻划。
3) contractible graph
可收缩的图
4) contractible subgraph
可收缩子图
5) E-S unretractive graphs
E-S不可收缩图
6) absolute approximative neighborhood retract
