Functional Clt for Random Walk among Bounded Random Conductances

ABSTRACT. We consider the nearest-neighbor simple random walk on Z, d ≥ 2, driven by a field of i.i.d. random nearest-neighbor conductances ωxy ∈ [0, 1]. Apart from the requirement that the bonds with positive conductances percolate, we pose no restriction on the law of the ω’s. We prove that, for a.e. realization of the environment, the path distribution of the walk converges weakly to that of...

Anomalous heat-kernel decay for random walk among bounded random conductances

We consider the nearest-neighbor simple random walk on Z, d ≥ 2, driven by a field of bounded random conductances ωxy ∈ [0, 1]. The conductance law is i.i.d. subject to the condition that the probability of ωxy > 0 exceeds the threshold for bond percolation on Z. For environments in which the origin is connected to infinity by bonds with positive conductances, we study the decay of the 2n-step ...

On two-dimensional random walk among heavy-tailed conductances

We consider a random walk among unbounded random conductances on the two-dimensional integer lattice. When the distribution of the conductances has an infinite expectation and a polynomial tail, we show that the scaling limit of this process is the fractional kinetics process. This extends the results of the paper [BČ10] where a similar limit statement was proved in dimension d ≥ 3. To make thi...

Note on the Heat-kernel Decay for Random Walk among Random Conductances with Heavy Tail

We study models of discrete-time, symmetric, Zd-valued random walks in random environments, driven by a field of i.i.d. randomnearest-neighbor conductances ωxy ∈ [0, 1], with polynomial tail near 0 with exponent γ > 0. For all d ≥ 4, we prove that the heat-kernel decay is as close as we want to the standard decay n−d/2 for large values of the parameter γ. keywords : Randomwalk, Random environme...

Anomalous Heat-kernel Decay for Random Walk among Polynomial Lower Tail Random Conductances

ABSTRACT. We consider the nearest-neighbor simple random walk on Zd, d ≥ 4, driven by a field of i.i.d. random nearest-neighbor conductances ωxy ∈ [0, 1]. Our aim is to derive estimates of the heat-kernel decay in a case where ellipticity assumption is absent. We consider the case of independant conductances with polynomial tail near 0 and obtain for almost every environment an anomalous lower ...
