非正曲率下时间平均在闭测地线周围的涨落

Fluctuations of time averages around closed geodesics in non-positive curvature

Daniel J. Thompson, Tianyu Wang

摘要:

研究秩为1的非正曲率闭流形的测地流。我们证明了一个渐近版本的中心极限定理的家庭的措施,从定期闭测地线收敛到Bowen-Margulis-Eschereper措施的最大熵。该技术扩展了Denker,Senti和Zhang的思想,他们证明了这种类型的渐近Lindeberg中心极限定理的周期轨道的扩张映射的规格性质。我们扩展这些技术从均匀的非均匀设置,从离散时间到连续时间。我们考虑只服从Lindeberg条件和弱正方差条件的Hölder观测量。如果我们假设一个自然加强的正方差条件,Lindeberg条件总是满足的。我们的结果扩展到动态阵列的霍尔德观测,并加权周期轨道措施收敛到一个独特的平衡态。

英文摘要:

We consider the geodesic flow for a rank one non-positive curvature closed manifold. We prove an asymptotic version of the Central Limit Theorem for families of measures constructed from regular closed geodesics converging to the Bowen-Margulis-Knieper measure of maximal entropy. The technique expands on ideas of Denker, Senti and Zhang, who proved this type of asymptotic Lindeberg Central Limit Theorem on periodic orbits for expansive maps with the specification property. We extend these techniques from the uniform to the non-uniform setting, and from discrete-time to continuous-time. We consider Hölder observables subject only to the Lindeberg condition and a weak positive variance condition. If we assume a natural strengthened positive variance condition, the Lindeberg condition is always satisfied. Our results extend to dynamical arrays of Hölder observables, and to weighted periodic orbit measures which converge to a unique equilibrium state.
