Quenched Exit Estimates and Ballisticity Conditions for Higher-dimensional Random Walk in Random Environment by Alexander Drewitz
Consider a random walk in an i.i.d. uniformly elliptic environment in dimensions larger than one. In 2002 Sznitman introduced for each γ ∈ (0, 1) the ballisticity condition (T )γ and the condition (T ′) defined as the fulfillment of (T )γ for each γ ∈ (0, 1). Sznitman proved that (T ′) implies a ballistic law of large numbers. Furthermore, he showed that for all γ ∈ (0.5, 1), (T )γ is equivalen...
متن کاملRandom Walk in a Random Multiplieative Environment
We investigate the dynamics of a random walk in a random multiplicative medium. This results in a random, but correlated, multiplicative process for the spatial distribution of random walkers. We show how the details of these correlations determine the asymptotic properties of the walk, i.e., the central limit theorem does not apply to these multiplicative processes. We also study a periodic so...
متن کاملRandom Walk in Random Environment: A Counterexample?
We describe a family of random walks in random environments which have exponentially decaying correlations, nearest neighbor transition probabilities which are bounded away from 0, and yet are subdiffusive in any dimension d < o e .
متن کاملLarge Deviations for Random Walk in a Random Environment
In this work, we study the large deviation properties of random walk in a random environment on Z with d ≥ 1. We start with the quenched case, take the point of view of the particle, and prove the large deviation principle (LDP) for the pair empirical measure of the environment Markov chain. By an appropriate contraction, we deduce the quenched LDP for the mean velocity of the particle and obta...
متن کاملTail estimates for one-dimensional random walk in random environment
Suppose that the integers are assigned i.i.d. random variables f! x g (taking values in the unit interval), which serve as an environment. This environment deenes a random walk fX k g (called a RWRE) which, when at x, moves one step to the right with probability ! x , and one step to the left with probability 1 ? ! x. Solomon (1975) determined the almost-sure asymptotic speed (=rate of escape) ...
