Velocity estimates for symmetric random walks at low ballistic disorder
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 …

Computable criteria for ballisticity of random walks in elliptic random environment
AF Ramírez, R Ribeiro - Electronic Journal of Probability, 2022 - projecteuclid.org
We consider random walks in iid elliptic random environments which are not uniformly
elliptic. We introduce a computable condition in dimension d= 2 and a general condition …
