Limit theorems for wobbly interval intermittent maps

Abstract

We consider perturbations of interval maps with indifferent fixed points, which we refer to as wobbly interval intermittent maps, for which stable laws for general H¨older observables fail. We obtain limit laws for such maps and H¨older observables. These limit laws are similar to the classical semistable laws previously established for random processes. One of the considered examples is an interval map with a countable number of discontinuities, and to analyse it we need to construct a Markov/Young tower.
