超度量空间之间的Z字形链与度量等价

Zig-zag chains and metric equivalences between ultrametric spaces

Álvaro Martínez-Pérez

摘要:

我们研究超度量空间的分类,基于它们的小尺度几何(一致同胚),大尺度几何(粗等价)和两者(所有尺度一致等价)。我们证明,这些等价的特点是并行建设使用组合工具称为共同之字形链。

英文摘要:

We study the classification of ultrametric spaces based on their small scale geometry (uniform homeomorphism), large scale geometry (coarse equivalence) and both (all scale uniform equivalences). We prove that these equivalences can be characterized with parallel constructions using a combinatoric tool called common zig-zag chain.
