Quenched exit estimates and ballisticity conditions for higher-dimensional random walk in random environment
Alexander Drewitz, Alejandro F. Ramírez
Consider a random walk in an i.i.d. uniformly elliptic environment in dimensions larger than one. In 2002, Sznitman introduced for each the ballisticity condition $(T)_…
