Abstract
We introduce the notion of localization at the boundary for conditioned random walks in i.i.d. and uniformly elliptic random environment on , in dimensions two and higher. If or 3, we prove localization for (almost) all walks. In contrast, for , there is a phase transition for environments of the form , where is an i.i.d. sequence of random variables, and ε represents the amount of disorder with respect to a simple random walk.
