A comparison principle for random walk on dynamical percolation

Probability 2020-01-16 v3

Abstract

We consider the model of random walk on dynamical percolation introduced by Peres, Stauffer and Steif (2015). We obtain comparison results for this model for hitting and mixing times and for the spectral-gap and log-Sobolev constant with the corresponding quantities for simple random walk on the underlying graph GG, for general graphs. When GG is the torus Znd\mathbb{Z}_n^d, we recover the results of Peres et al. and we also extend them to the critical case. We also obtain bounds in the cases where GG is a transitive graph of moderate growth and also when it is the hypercube.
