Statistical properties of unimodal maps: the quadratic family

Artur Avila, Carlos Gustavo Moreira

Published 2000-10-06, updated 2003-06-10Version 5

We prove that almost every non-regular real quadratic map is Collet-Eckmann and has polynomial recurrence of the critical orbit (proving a conjecture by Sinai). It follows that typical quadratic maps have excellent ergodic properties, as exponential decay of correlations (Keller and Nowicki, Young) and stochastic stability in the strong sense (Baladi and Viana). This is an important step to get the same results for more general families of unimodal maps.
