CENTRAL LIMIT THEOREM FOR RANDOM WALKS IN DIVERGENCE FREE RANDOM DRIFT FIELD – REVISITED
CENTRAL LIMIT THEOREM FOR RANDOM WALKS IN DIVERGENCE FREE RANDOM DRIFT FIELD – REVISITED
In Kozma–Toth (2017), the weak CLT was established for random walks in doubly stochastic (or, divergence-free) random environments, under the following conditions: Strict ellipticity assumed for the symmetric part of the drift field. H−1 assumed for the antisymmetric part of the drift field. The proof relied on a martingale approximation …
