Limits of equilibrium states for coupled weakly interacting systems. Application to the measure of maximal entropy

Renaud Leplaideur

We study metastability for symbolic dynamic. We prove that for a global system given by two independent sub-systems linked by a hole, and for a Lipschitz continuous potential, the…

Zeta functions and the Fried conjecture for smooth pseudo-Anosov flows

Malo Jézéquel, Jonathan Zung

To a transitive pseudo-Anosov flow on a -manifold and a representation of , we associate a zeta function defined for , generalizing…

Quantitative recurrence for tranformation

Françoise Pène, Benoit Saussol

We are interested in the study of the asymptotic behaviour of return times in small balls for the -transformation. We exhibit different asymptotic behaviours (different s…

An Estimation of Phase Transition

Shamsa Ishaq, Renaud Leplaideur

In [8], H. Bruin and R. Leplaideur studied a class of potentials such that the pressure function exhibit a phase transition at a parameter \b{eta}c > 0. This paper will prove that…

Rates in almost sure invariance principle for nonuniformly hyperbolic maps

C Cuny, J Dedecker, A Korepanov +1

We prove the Almost Sure Invariance Principle (ASIP) with close to optimal error rates for nonuniformly hyperbolic maps. We do not assume exponential contraction along stable leave…

The Jacaranda tree is strongly aperiodic and has zero entropy

Alexandre Baraviera, Renaud Leplaideur

We prove that the Jacaranda tree obtained as a fixed point for a substreetution in previous work of the authors is strongly aperiodic and that the number of patches increases linea…

Expansions in the local and the central limit theorems for dynamical systems

Kasun Fernando, Françoise Pène

We study higher order expansions both in the Berry-Esséen estimate (Edgeworth expansions) and in the local limit theorems for Birkhoff sums of chaotic probability preserving dynami…

Application of the convergence of the spatio-temporal processes for visits to small sets

Françoise Pène, Benoit Saussol

The goal of this article is to point out the importance of spatio-temporal processes in different questions of quantitative recurrence. We focus on applications to the study of the…

Nonlinear thermodynamical formalism

Jérôme Buzzi, Benoît Kloeckner, Renaud Leplaideur

We define a nonlinear thermodynamical formalism which translates into dynamical system theory the statistical mechanics of generalized mean-field models, extending investigation of…

Sharp error term in local limit theorems and mixing for Lorentz gases with infinite horizon

Francoise Pène, Dalia Terhesiu

We obtain sharp error rates in the local limit theorem for the Sinai billiard map (one and two dimensional) with infinite horizon. This result allows us to further obtain higher or…

Resolvent conditions and growth of powers of operators

Guy Cohen, Christophe Cuny, Tanja Eisner +1

Following Bermúdez et al. (ArXiv: 1706.03638v1), we study the rate of growth of the norms of the powers of a linear operator, under various resolvent conditions or Cesàro boundedne…

Local limit theorem for randomly deforming billiards

Mark F. Demers, Francoise Pene, Hong-Kun Zhang

We study limit theorems in the context of random perturbations of dispersing billiards in finite and infinite measure. In the context of a planar periodic Lorentz gas with finite h…

Large deviation for return times

Adriana Coutinho, Jerome Rousseau, Benoit Saussol

We prove a large deviation result for return times of the orbits of a dynamical system in a -neighbourhood of an initial point . Our result may be seen as a differentiable ve…

Rates in almost sure invariance principle for slowly mixing dynamical systems

C. Cuny, J. Dedecker, A. Korepanov +1

We prove the one-dimensional almost sure invariance principle with essentially optimal rates for slowly (polynomially) mixing deterministic dynamical systems, such as Pomeau-Mannev…

Mixing rate in infinite measure for Z^d-extension, application to the periodic Sinai billiard

Françoise Pène

We study the rate of mixing of observables of Z^d-extensions of probability preserving dynamical systems. We explain how this question is directly linked to the local limit theorem…

Generalized Curie-Weiss Model and Quadratic Pressure in Ergodic Theory

R. Leplaideur, F. Watbled

We explain the Curie Weiss model in Statistical Mechanics within the Ergodic viewpoint. More precisely, we simultaneously define in , on the one hand a gene…

Thermodynamic formalism and Substitutions

Nicolas Bedaride, Pascal Hubert, Renaud Leplaideur

This paper studies properties of a Renormalization Operator for potentials in symbolic dynamics. These operators first appeared in \cite{BLL} and the link with substitutions was do…

Stochastic Variational Inequalities on Non-Convex Domains

Rainer Buckdahn, Lucian Maticiuc, Etienne Pardoux +1

The objective of this work is to prove, in a first step, the existence and the uniqueness of a solution of the following multivalued deterministic differential equation: $dx(t)+\pa…

Multiple mixing from weak hyperbolicity by the Hopf argument

Yves Coudène, Boris Hasselblatt, Serge Troubetzkoy

We show that using only weak hyperbolicity (no smoothness, compactness or exponential rates) the Hopf argument produces multiple mixing in an elementary way. While this recovers cl…
