时周期流的时变

Time-Changes of Horocycle Flows

Giovanni Forni, Corinna Ulcigrai

摘要:

本文考虑紧致双曲曲面上单位切丛上经典时环流的光滑时变,证明了等分布率和混合率的严格界。然后,我们推导出的频谱上的光滑时变,并表明,频谱是绝对连续的勒贝格测度的实线和最大的频谱类型是等价的勒贝格。

英文摘要:

We consider smooth time-changes of the classical horocycle flows on the unit tangent bundle of a compact hyperbolic surface and prove sharp bounds on the rate of equidistribution and the rate of mixing. We then derive results on the spectrum of smooth time-changes and show that the spectrum is absolutely continuous with respect to the Lebesgue measure on the real line and that the maximal spectral type is equivalent to Lebesgue.
