On equivalence of quenched and annealed statistical properties for conservative IID random dynamical systems

Abstract

Abstract In this paper, we prove several theorems relating annealed exponential mixing of the two-point motion with quenched properties of the one-point motion for conservative IID random dynamical systems. In particular, we show that annealed exponential mixing of the two-point motion implies quenched exponential mixing of the one-point motion. We also show that if the two-point motion satisfies annealed exponential mixing and the annealed central limit theorem with polynomial rate of convergence, then the one-point motion satisfies a quenched CLT. These results hold for all Hölder and Sobolev spaces of positive index. This establishes the quenched CLT in many new cases.
