AI总结:

该研究针对中心方向主要扩张的非平稳异混沌面包映射,通过构造Gibbs-Markov诱导映射,建立了其相关性衰减、正态近似等统计性质的相关定理,得到了多元CLT收敛速率的具体估计。

AI中文摘要:

我们研究了一系列异混沌面包映射的非平稳复合映射的统计性质。对于中心方向主要为扩张的映射,我们建立了三个主要结果:一类广泛测度的记忆损失指数速率(定理1.1)、带拉伸指数衰减的函数相关性界(定理1.2)以及Wasserstein-1距离下多元中心极限定理(CLT)的误差界(定理1.3)。证明基于为非平稳复合映射构造合适的Gibbs-Markov诱导映射。在某一特殊情形下,我们得到了多元CLT收敛速率的具体估计(定理1.4)。

英文摘要:

We study statistical properties of nonstationary compositions of a sequence of heterochaos baker maps. For maps whose central direction is mostly expanding, we establish three main results: exponential rate of memory loss for a broad class of measures (Theorem 1.1), a functional correlation bound with stretched exponential decay (Theorem 1.2), and an error bound for the multivariate central limit theorem (CLT) in the Wasserstein-1 distance (Theorem 1.3). The proofs are based on the construction of suitable Gibbs--Markov induced maps for the nonstationary compositions. In a certain special case we obtain a concrete estimate on the rate of convergence in the multivariate CLT (Theorem 1.4).
