Almost sure rates of mixing for random intermittent maps

Abstract

We consider a family F\mathcal F of maps with two branches and a common neutral fixed point 00 such that the order of tangency at 00 belongs to some interval [α0,α1](0,1)[\alpha_0, \alpha_1]\subset (0, 1). Maps in F\mathcal F do not necessarily share a common Markov partition. At each step a member of F\mathcal F is chosen independently with respect to the uniform distribution on [α0,α1][\alpha_0, \alpha_1]. We show that the construction of the random tower in Bahsoun-Bose-Ruziboev \cite{BBR} with \emph{general return time} can be carried out for random compositions of such maps. Thus their general results are applicable and gives upper bounds for the quenched decay of correlations of form n11/α0+δn^{1-1/\alpha_0+\delta} for any δ>0\delta>0.
