Large deviations and phase transition for random walks in random nonnegative potentials
چکیده انگلیسی

We establish large deviation principles and phase transition results for both quenched and annealed settings of nearest-neighbor random walks with constant drift in random nonnegative potentials on ZdZd. We complement the analysis of M.P.W. Zerner [Directional decay of the Green’s function for a random nonnegative potential on ZdZd, Ann. Appl. Probab. 8 (1996) 246–280], where a shape theorem on the Lyapunov functions and a large deviation principle in absence of the drift are achieved for the quenched setting.
