Compound Poisson approximation for simple transient random walks in random sceneries

Nicolas Chenavier, Ahmad Darwiche, Arnaud Rousselle

Given a simple transient random walk $(S_{n})_{n \geq 0}$ in $Z$ and a stationary sequence of real random variables $(ξ (s))_{s \in Z}$ , we investigate the extremes of…

Some properties on extremes for transient random walks in random sceneries

Nicolas Chenavier, Ahmad Darwiche

Let $(S_{n})_{n \geq 0}$ be a transient random walk in the domain of attraction of a stable law and let $(ξ (s))_{s \in Z}$ be a stationary sequence of random variables. In a…

Point processes of exceedances for random walks in random sceneries

Ahmad Darwiche

Let ${ξ (k), k \in Z}$ be a stationary sequence of random variables and let ${S_{n}, n \in N_{+}}$ be a transient random walk in the domain of attraction of a st…

Convergence of weighted ergodic averages

Ahmad Darwiche, Dominique Schneider

Let $(X, A, μ)$ be a probability space and let $T$ be a contraction on $L^{2} (μ)$ . We provide suitable conditions over sequences $(w_{k})$ , $(u_{k})$ and $(A_{k})$ in such a way t…

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

Nicolas Chenavier, Ahmad Darwiche

Let ${ξ (k), k \in Z}$ be a stationary sequence of random variables with conditions of type $D (u_{n})$ and $D^{'} (u_{n})$ . Let ${S_{n}, n \in N}$ be a transient rando…
