Ballisticity of Random Walks in Random Environments on Z with Bounded Jumps
2022, v.28, Issue 5, 659-671
We characterize ballistic behavior for general i.i.d.\ random walks in random environments on Z with bounded jumps. The two characterizations we provide do not use uniform ellipticity conditions. They are natural in the sense that they both relate to formulas for the limiting speed in the nearest-neighbor case.
