Central limit theorems for sequential and random intermittent dynamical systems

M Nicol, A Török, S Vaienti - Ergodic Theory and Dynamical Systems, 2018 - cambridge.org
We establish self-norming central limit theorems for non-stationary time series arising as
observations on sequential maps possessing an indifferent fixed point. These …

Loss of memory and moment bounds for nonstationary intermittent dynamical systems

A Korepanov, J Leppänen - Communications in Mathematical Physics, 2021 - Springer
We study nonstationary intermittent dynamical systems, such as compositions of a
(deterministic) sequence of Pomeau–Manneville maps. We prove two main results: sharp …

Projective cones for sequential dispersing billiards

MF Demers, C Liverani - Communications in Mathematical Physics, 2023 - Springer
We construct Birkhoff cones for dispersing billiards, which are contracted by the action of the
transfer operator. This construction permits the study of statistical properties not only of …

Quasistatic dynamics with intermittency

J Leppänen, M Stenlund - Mathematical Physics, Analysis and Geometry, 2016 - Springer
We study an intermittent quasistatic dynamical system composed of nonuniformly hyperbolic
Pomeau–Manneville maps with time-dependent parameters. We prove an ergodic theorem …

Functional correlation decay and multivariate normal approximation for non-uniformly expanding maps

J Leppänen - Nonlinearity, 2017 - iopscience.iop.org
In the setting of intermittent Pomeau–Manneville maps with time dependent parameters, we
show a functional correlation bound widely useful for the analysis of the statistical properties …

[PDF][PDF] Projective cones for generalized dispersing billiards

MF Demers, C Liverani - arXiv preprint arXiv:2104.06947, 2021 - faculty.fairfield.edu
We construct Birkhoff cones for dispersing billiards, which are contracted by the action of the
transfer operator. This construction permits the study of statistical properties not only of …

The pressure function for infinite equilibrium measures

H Bruin, D Terhesiu, M Todd - Israel Journal of Mathematics, 2019 - Springer
Assume that (X, f) is a dynamical system and φ: X→−∞,∞) is a potential such that the f-
invariant measure μ φ equivalent to the φ-conformal measure is infinite, but that there is an …

Robustness of ergodic properties of non-autonomous piecewise expanding maps

M Tanzi, T Pereira, S van Strien - Ergodic Theory and Dynamical …, 2019 - cambridge.org
Recently, there has been an increasing interest in non-autonomous composition of
perturbed hyperbolic systems: composing perturbations of a given hyperbolic map …

Sunklodas' approach to normal approximation for time-dependent dynamical systems

J Leppänen, M Stenlund - Journal of Statistical Physics, 2020 - Springer
We consider time-dependent dynamical systems arising as sequential compositions of self-
maps of a probability space. We establish conditions under which the Birkhoff sums for …

Central limit theorems with a rate of convergence for time-dependent intermittent maps

O Hella, J Leppänen - Stochastics and Dynamics, 2020 - World Scientific
We study dynamical systems arising as time-dependent compositions of Pomeau-
Manneville-type intermittent maps. We establish central limit theorems for appropriately …
