Subexponential decay of correlations for compact group extensions of non-uniformly expanding systems
نویسندگان
چکیده
We show that the renewal theory developed by Sarig and Gouëzel in the context of nonuniformly expanding dynamical systems applies also to the study of compact group extensions of such systems. As a consequence, we obtain results on subexponential decay of correlations for equivariant Hölder observations.

Markov Structures and Decay of Correlations for Non-uniformly Expanding Dynamical Systems
We consider non-uniformly expanding maps on compact Riemannian manifolds of arbitrary dimension, possibly having discontinuities and/or critical sets, and show that under some general conditions they admit an induced Markov tower structure for which the decay of the return time function can be controlled in terms of the time generic points need to achieve some uniform expanding behavior. As a c...
متن کاملExtreme Value Distributions for some classes of Non-Uniformly Partially Hyperbolic Dynamical Systems
In this note, we obtain verifiable sufficient conditions for the extreme value distribution for a certain class of skew product extensions of non-uniformly hyperbolic base maps. We show that these conditions, formulated in terms of the decay of correlations on the product system and the measure of rapidly returning points on the base, lead to a distribution for the maximum of Φ(p) = − log(d(p, ...
متن کاملMixing and Decay of Correlations in Non-uniformly Expanding Maps: a Survey of Recent Results
We discuss recent results on decay of correlations for non-uniformly expanding maps. Throughout the discussion, we address the question of why different dynamical systems have different rates of decay of correlations and how this may reflect underlying geometrical characteristics of the system.
متن کاملCorrelations Decay for Markov Maps on a Countable States Space
We estimate the decay of correlations for some Markov maps on a countable states space. A necessary and suucient condition is given for the transfer operator to be quasi-compact on the space of locally Lipschitz functions. In the non quasi-compact case, the decay of correlations depends on the contribution to the transfer operator of the complementary of nitely many cylinders. Estimates are giv...
