Random walks in random environment: what a single trajectory tells

Auteur(s):

Code(s) de Classification MSC:

Résumé: We present a procedure that determines the law of a random walk in an iid random environment as a function of a single "typical" trajectory. We indicate when the trajectory characterizes the law of the environment, and we say how this law can be determined. We then show how independent trajectories having the distribution of the original walk can be generated as functions of the single observed trajectory.

Mots Clés: Random walks in random environment ; reinforced random walks
