On the entropy of Japanese continued fractions

L Luzzi, S Marmi - arXiv preprint math/0601576, 2006 - arxiv.org
We consider a one-parameter family of expanding interval maps $\{T_ {\alpha}\} _ {\alpha\in
[0, 1]} $(japanese continued fractions) which include the Gauss map ($\alpha= 1$) and the …

Continuity of SRB measure and entropy for Benedicks–Carleson quadratic maps

JM Freitas - Nonlinearity, 2005 - iopscience.iop.org
We consider the quadratic family of maps given by fa (x)= 1− ax 2 on I=[− 1, 1], for the
Benedicks–Carleson parameters. On this positive Lebesgue measure set of parameters …

Statistical stability and limit laws for Rovella maps

JF Alves, M Soufi - Nonlinearity, 2012 - iopscience.iop.org
We consider a family of one-dimensional maps arising from the contracting Lorenz attractors
studied by Rovella. Benedicks–Carleson techniques were used by Rovella to prove that …

Geometry of expanding absolutely continuous invariant measures and the liftability problem

JF Alves, CL Dias, S Luzzatto - Annales de l'Institut Henri Poincaré C …, 2013 - Elsevier
We show that for a large class of maps on manifolds of arbitrary finite dimension, the
existence of a Gibbs–Markov–Young structure (with Lebesgue as the reference measure) is …

Statistical stability and continuity of SRB entropy for systems with Gibbs-Markov structures

JF Alves, M Carvalho, JM Freitas - Communications in Mathematical …, 2010 - Springer
We present conditions on families of diffeomorphisms that guarantee statistical stability and
SRB entropy continuity. They rely on the existence of horseshoe-like sets with infinitely many …

A variational problem in the mechanics of complex materials

M Giaquinta, P Mariano, G Modica - Discrete and Continuous …, 2010 - ricerca.sns.it
We analyze the possible nucleation of cracked surfaces in materials in which changes in the
material texture have a prominent influence on the macroscopic mechanical behavior. The …

Hard bifurcations in dynamical systems with bounded random perturbations

A Homburg, T Young - Regular and Chaotic Dynamics, 2006 - mathnet.ru
We study bifurcations in dynamical systems with bounded random perturbations. Such
systems, which arise quite naturally, have been nearly ignored in the literature, despite a …

Entropy formula and continuity of entropy for piecewise expanding maps

JF Alves, A Pumariño - Annales de l'Institut Henri Poincaré C, Analyse non …, 2021 - Elsevier
We consider some classes of piecewise expanding maps in finite dimensional spaces
having invariant probability measures which are absolutely continuous with respect to …

Physical measures for infinite-modal maps

V Araujo, MJ Pacifico - arXiv preprint math/0411493, 2004 - arxiv.org
We analyze certain parametrized families of one-dimensional maps with infinitely many
critical points from the measure-theoretical point of view. We prove that such families have …
