群的收缩边界上的可度量化拓扑

A Metrizable Topology on the Contracting Boundary of a Group

Christopher H. Cashen, John M. Mackay

摘要:

真测地度量空间的“收缩边界”由表现为双曲空间中的射线的测地射线的等价类组成。我们引入了一个几何相关的,拟等距不变的拓扑收缩边界。当空间是有限生成群的Cayley图时,我们证明了新拓扑是可度量化的.

英文摘要:

The 'contracting boundary' of a proper geodesic metric space consists of equivalence classes of geodesic rays that behave like rays in a hyperbolic space. We introduce a geometrically relevant, quasi-isometry invariant topology on the contracting boundary. When the space is the Cayley graph of a finitely generated group we show that our new topology is metrizable.
