关于可逆马氏过程极限定理的注记

Remarks on limit theorems for reversible Markov processes

Martial Longla

摘要:

本文对可逆马尔可夫链的函数提出了一些向后-向前鞅分解。利用这些分解证明了部分和方差渐近线性的可逆马尔可夫链的泛函CLT。我们还提供了一个证明之间的等价性的渐近线性的方差和收敛的积分$1/(1-t)$相对于相关的谱测度$ρ$。我们还研究了平稳可逆马尔可夫链的零平方可积〔的〕函数作为新息的线性过程的渐近性态。我们应用这项研究的几种情况下,出现在回归估计的可逆平稳马尔可夫链。

英文摘要:

We propose some backward-forward martingale decompositions for functions of reversible Markov chains. These decompositions are used to prove the functional CLT for reversible Markov chains with asymptotically linear variance of partial sums. We also provide a proof of the equivalence between asymptotic linearity of the variance and convergence of the integral of $1/(1-t)$ with respect to the associated spectral measure $ρ$. We also study the asymptotic behavior of linear processes having as innovations mean zero square integrable functions of stationary reversible Markov chains. We apply this study to several cases of reversible stationary Markov chains that arise in regression estimation.
