Almost sure invariance principle for sequential and non-stationary dynamical systems (1406.4266v1)
Published 17 Jun 2014 in math.DS
Abstract: We establish almost sure invariance principles, a strong form of approximation by Brownian motion, for non-stationary time-series arising as observations on dynamical systems. Our examples include observations on sequential expanding maps, perturbed dynamical systems, non-stationary sequences of functions on hyperbolic systems as well as applications to the shrinking target problem in expanding systems.
