Hitting time statistics and extreme value theory

ACM Freitas, JM Freitas, M Todd - Probability Theory and Related Fields, 2010 - Springer
We consider discrete time dynamical systems and show the link between Hitting Time
Statistics (the distribution of the first time points land in asymptotically small sets) and …

[HTML][HTML] Martingale–coboundary decomposition for families of dynamical systems

A Korepanov, Z Kosloff, I Melbourne - Annales de l'Institut Henri Poincaré C …, 2018 - Elsevier
We prove statistical limit laws for sequences of Birkhoff sums of the type∑ j= 0 n− 1 vn∘ T nj
where T n is a family of nonuniformly hyperbolic transformations. The key ingredient is a new …

From rates of mixing to recurrence times via large deviations

JF Alves, JM Freitas, S Luzzatto, S Vaienti - Advances in Mathematics, 2011 - Elsevier
A classic approach in dynamical systems is to use particular geometric structures to deduce
statistical properties, for example the existence of invariant measures with stochastic-like …

Explicit coupling argument for non-uniformly hyperbolic transformations

A Korepanov, Z Kosloff, I Melbourne - Proceedings of the Royal …, 2019 - cambridge.org
The transfer operator corresponding to a uniformly expanding map enjoys good spectral
properties. We verify that coupling yields explicit estimates that depend continuously on the …

Quantitative statistical stability, speed of convergence to equilibrium and partially hyperbolic skew products

S Galatolo - Journal de l'École polytechnique …, 2018 - jep.centre-mersenne.org
We consider a general relation between fixed point stability of suitably perturbed transfer
operators and convergence to equilibrium (a notion which is strictly related to decay of …

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 …

Absolutely continuous invariant measures for non-uniformly expanding maps

H Hu, S Vaienti - Ergodic Theory and Dynamical Systems, 2009 - cambridge.org
For a large class of non-uniformly expanding maps of ℝm, with indifferent fixed points and
unbounded distortion and that are non-necessarily Markovian, we construct an absolutely …

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 …

Statistical stability of mostly expanding diffeomorphisms

M Andersson, CH Vásquez - Annales de l'Institut Henri Poincaré C …, 2020 - Elsevier
We study how physical measures vary with the underlying dynamics in the open class of C r,
r> 1, strong partially hyperbolic diffeomorphisms for which the central Lyapunov exponents …
