摘要
We prove a counterpart of exponential decay of correlations for certain non-stationary systems. Namely, given two probability measures absolutely continuous with respect to a reference measure, their quasi-Holder distance (and in particular their L-1 distance) decreases exponentially under action by compositions of arbitrarily chosen maps close to those that are both piecewise expanding and mixing in a certain sense.
