弱独立条件下随机场景中瞬态随机游动的极值

Extremes for transient random walks in random sceneries under weak independence conditions

Nicolas Chenavier, Ahmad Darwiche

摘要:

设$\{ξ(k), k \in \mathbb{Z} \}$是具有$D(u_n)$和$D'(u_n)$类型条件的平稳随机变量序列。设$\{S_n, n \in \mathbb{N} \}$是稳定律的吸引区域中的瞬态随机游动。当$n$趋于无穷大时,我们给出了序列$\{ξ(S_n), n \in \mathbb{N} \}$的第一个$n$项的最大值的极限定理.本文推广了Franke和Saigo关于序列$\{ξ(k), k \in \mathbb{Z} \}$是独立同分布的情形的一个结果。

英文摘要:

Let $\{ξ(k), k \in \mathbb{Z} \}$ be a stationary sequence of random variables with conditions of type $D(u_n)$ and $D'(u_n)$. Let $\{S_n, n \in \mathbb{N} \}$ be a transient random walk in the domain of attraction of a stable law. We provide a limit theorem for the maximum of the first $n$ terms of the sequence $\{ξ(S_n), n \in \mathbb{N} \}$ as $n$ goes to infinity. This paper extends a result due to Franke and Saigo who dealt with the case where the sequence $\{ξ(k), k \in \mathbb{Z} \}$ is i.i.d.
