Empirical processes for recurrent and transient random walks in random scenery
ESAIM: Probability and Statistics, Tome 24 (2020), pp. 127-137.

In this paper, we are interested in the asymptotic behaviour of the sequence of processes (W$$(s,t))$$ with

$$

where (ξ$$, x ∈ ℤ$$) is a sequence of independent random variables uniformly distributed on [0, 1] and (S$$)$$ is a random walk evolving in ℤ$$, independent of the ξ’s. In M. Wendler [Stoch. Process. Appl. 126 (2016) 2787–2799], the case where (S$$)$$ is a recurrent random walk in ℤ such that (n$$S$$)$$ converges in distribution to a stable distribution of index α, with α ∈ (1, 2], has been investigated. Here, we consider the cases where (S$$)$$ is either:

(a) a transient random walk in ℤ$$,

(b) a recurrent random walk in ℤ$$ such that (n$$S$$)$$ converges in distribution to a stable distribution of index d ∈{1, 2}.
