摘要：We consider the simple random walk in i.i.d. nonnegative potentials onthe multidimensional cubic lattice. Our goal is to investigate the cost paid by thesimple random walk for traveling from the origin to a remote location in a landscapeof potentials. In particular, we obtain concentration inequalities for the travel costin unbounded nonnegative potentials.
