论文摘要
让$ g $成为至少$ 14 $的顶点的关键$ 5 $连接图。如果在v_ {4}（g）中有一个顶点$ x \，以至于$ g [n_ {g}（x）] \ cong k_ {1,3} $或$ g [n_ {g}（x）（x）] $ 0 <\ | v（h）\ | <4 $。
Let $G$ be a contraction critically quasi $5$-connected graph on at least $14$ vertices. If there is a vertex $x\in V_{4}(G)$ such that $G[N_{G}(x)]\cong K_{1,3}$ or $G[N_{G}(x)]\cong C_{4}$, then $G$ has a quasi $5$-contractible subgraph $H$ such that $0<\|V(H)\|<4$.
