快速混合流中的收缩目标和负曲流形上的测地流

Shrinking targets in fast mixing flows and the geodesic flow on negatively curved manifolds

Stefano Galatolo, Isaia Nisoli

摘要:

我们证明了在具有不变测度的快速混合流中,到达给定截面所需的时间与该截面处测度的一种条件维数有关。将所得结果应用于紧致变负截面曲率流形的测地流,建立了这类流的对数律。

英文摘要:

We show that in a rapidly mixing flow with an invariant measure, the time which is needed to hit a given section is related to a sort of conditional dimension of the measure at the section. The result is applied to the geodesic flow of compact variable negative sectional curvature manifolds, establishing a logarithm law for such kind of flow.
