CAT(0)空间的渐近几何正则性

Asymptotic geometric regularity of CAT(0) spaces

University of Tsukuba(筑波大学)

Koichi Nagano

AI总结:

该研究证明了CAT(0)空间在特定条件下与欧几里得空间的双Lipschitz同胚性,并应用此结果得出CAT(1)空间的同胚结论。

摘要:

我们证明,如果一个n维的测地完备CAT(0)空间的蒂斯边界足够接近(n-1)维标准单位球面,则它与n维欧几里得空间是双Lipschitz同胚的。作为应用,我们得出结论:如果一个(n-1)维测地完备CAT(1)空间足够接近(n-1)维标准单位球面,则它们彼此是双Lipschitz同胚的。

英文摘要:

We prove that if an n-dimensional geodesically complete CAT(0) space has Tits boundary sufficiently close to the (n-1)-dimensional standard unit sphere, then it is bi-Lipschiz homeomorphic to the n-dimensional Euclidean space. As an application, we conclude that if an (n-1)-dimensional geodesically complete CAT(1) space is sufficiently close to the (n-1)-dimensional standard unit sphere, then they are bi-Lipschiz homeomorphic to each other.
