1) contraction critical
收缩临界
1.
It is proved that any contraction critical 5-connected graph on n vertices has at least n+1 trivially non-contractible edges.
证明n个顶点的收缩临界5连通图中至少有n+1条平凡不可收缩边。
2.
In this paper we study mainly some problems about the contraction critical kconnected graph.
本文主要研究收缩临界k连通图，如果将k连通图G中的一条边收缩之后所得到的图仍然是k连通图，则称这条边为G的k可收缩边，简称可收缩边，否则称为不可收缩边。
3.
Let G be a contraction critical 5-connected graph,x∈V(G),d(x)≥ 6 and x1,x2∈N(x)∩V5(G).
当G是收缩临界5连通图,x∈V(G)且d(x)≥6,x1,x2为与x相邻的5度点时,证明如果x1x2∈E(G),则x与3个5度点相邻。
