临界情形下随机递归的不变测度

On invariant measures of stochastic recursions in a critical case

Dariusz Buraczewski

摘要:

考虑$\mathbb{R}$上的自回归模型,由递推方程$X_n=A_nX_{n-1}+B_n$定义,其中$\{(B_n,A_n)\}$是独立同分布的.值为$\mathbb{R}\times\mathbb{R}^+$和$\mathbb {E}[\log A_1]=0$的随机变量(临界情况)。Babillot,Bougerol和Elie证明了过程$\{X_n\}$存在唯一不变Radon测度.本文的目的是研究它在无穷远处的行为。我们还描述了其他两个随机递归,包括排队论中产生的平稳措施。

英文摘要:

We consider an autoregressive model on $\mathbb{R}$ defined by the recurrence equation $X_n=A_nX_{n-1}+B_n$, where $\{(B_n,A_n)\}$ are i.i.d. random variables valued in $\mathbb{R}\times\mathbb{R}^+$ and $\mathbb {E}[\log A_1]=0$ (critical case). It was proved by Babillot, Bougerol and Elie that there exists a unique invariant Radon measure of the process $\{X_n\}$. The aim of the paper is to investigate its behavior at infinity. We describe also stationary measures of two other stochastic recursions, including one arising in queuing theory.
