对称秩1空间的无穷远边界

Boundary at infinity of symmetric rank one spaces

Sergei Buyalo, Alexey Kuznetsov

摘要:

我们证明了定义在非紧型秩为1的对称空间无穷远边界上的标准Carnot-Caratheodory球面度量和准球面度量是可视的,即,它们分别在无穷远处的空间上和边界上与Gromov乘积的逆指数具有泛bilipschitz常数的bilipschitz等价.

英文摘要:

We show that canonical Carnot-Caratheodory spherical and horospherical metrics, which are defined on the boundary at infinity of every rank one symmetric space of non-compact type, are visual, i.e., they are bilipschitz equivalent with universal bilipschitz constants to the inverse exponent of Gromov products based in the space and on the boundary at infinity respectively.
