PERSISTENCE EXPONENT FOR RANDOM WALK ON DIRECTED VERSIONS OF Z 2
Résumé
We study the persistence exponent for random walks in random sceneries (RWRS) with integer values and for some special random walks in random environment in Z 2 including random walks in Z 2 with random orientations of the horizontal layers.
