AI总结:

本文定义了一种类似于Gromov-Hausdorff距离的距离,用于比较任意拟等距空间,并研究了在该距离下极限保持的性质以及全体度量空间类赋予该距离后的性质。

摘要:

我们定义了一种类似于Gromov-Hausdorff距离的距离,使得可以比较任意拟等距空间。我们还研究了在该距离下极限保持的性质,以及赋予该距离的整个度量空间类的性质。为此,我们引入了对应关系的拟等距畸变概念。利用这一概念,我们证明了所有度量空间类是道路连通的;事实上,任意两个度量空间可以通过一条有限长度的曲线连接。

英文摘要:

We define a distance analogous to the Gromov-Hausdorff distance that enables the comparison of arbitrary quasi-isometric spaces. We also investigate properties preserved under limits with respect to this distance, as well as properties of the entire class of metric spaces equipped with this distance. For this purpose, we introduce the notion of quasi-isometric distortion for correspondences. Using this notion, we prove that the class of all metric spaces is path-connected; in fact, any two metric spaces can be connected by a curve of finite length.
