Abstract

In this paper, we obtain almost sure invariance principles with rate of order \(n^{1/p}\log ^\beta n\), \(2< p\le 4\), for sums associated with a sequence of reverse martingale differences. Then, we apply those results to obtain similar conclusions in the context of some non-invertible dynamical systems. For instance, we treat several classes of maps of the interval (for possibly unbounded observables) or smooth dynamical systems under a very weak regularity condition on the observables.
