一个强的对相关界意味着西奈台球的CLT

A strong pair correlation bound implies the CLT for Sinai Billiards

Mikko Stenlund

摘要:

对于动力系统,复相关的强界蕴含着中心极限定理(CLT)[ChMa]。在Biltov的论文[Ch2]中,对离散台球的动态Holder连续可观量导出了这样一个界。在这里,我们削弱了规律性的假设,并随后表明,复相关的界限直接从对相关的界限。因此,对于更广泛的一类可观测量,仅对相关性的强约束就意味着CLT。结果推广到任意维的Anosov同构。

英文摘要:

For Dynamical Systems, a strong bound on multiple correlations implies the Central Limit Theorem (CLT) [ChMa]. In Chernov's paper [Ch2], such a bound is derived for dynamically Holder continuous observables of dispersing Billiards. Here we weaken the regularity assumption and subsequently show that the bound on multiple correlations follows directly from the bound on pair correlations. Thus, a strong bound on pair correlations alone implies the CLT, for a wider class of observables. The result is extended to Anosov diffeomorphisms in any dimension.
