粗压实和受控产品

Coarse compactifications and controlled products

Tomohiro Fukaya, Shin-ichi Oguni, Takamitsu Yamauchi

摘要:

我们在度量空间上引入了控制乘积的概念,作为Gromov乘积的推广,并利用控制乘积构造了边界,我们称之为Gromov边界.证明了在适当的度量空间上关于控制积的Gromov边界作为粗紧化补充了该空间。它还表明,有一个双射之间的控制产品的所有粗等价类的集合和粗紧化的所有等价类的集合的对应。

英文摘要:

We introduce the notion of controlled products on metric spaces as a generalization of Gromov products, and construct boundaries by using controlled products, which we call the Gromov boundaries. It is shown that the Gromov boundary with respect to a controlled product on a proper metric space complements the space as a coarse compactification. It is also shown that there is a bijective correspondence between the set of all coarse equivalence classes of controlled products and the set of all equivalence classes of coarse compactifications.
