摘要
We derive asymptotic estimates for the velocity of random walks in random environments which are perturbations of the simple symmetric random walk but have a small local drift in a given direction. Our estimates complement previous results presented by Sznitman in [16] and are in the spirit of expansions obtained by Sabot in [11].
