论文摘要
我们证明了$ \ mathrm {qi}^{+}（\ mathbb {r}）$ presentation-preserientation-preserving the Real Line的Quasi iSometries是一个可左定的，不可用的群体，它们无法在实际线路上有效地作用于实线$ \ Mathbb {r} $ \ $ \ Mathbb {r}。$。
We prove that the group $\mathrm{QI}^{+}(\mathbb{R})$ of orientation-preserving quasi-isometries of the real line is a left-orderable, non-simple group, which cannot act effectively on the real line $\mathbb{R}.$
