On the conservative pasting lemma
Pedro Teixeira
Several perturbation tools are established in the volume preserving setting allowing for the pasting, extension, localized smoothing and local linearization of vector fields. The p…
Extreme Value Laws for dynamical systems with countable extremal sets
Davide Azevedo, Ana Cristina Moreira Freitas, Jorge Milhazes Freitas +1
We consider stationary stochastic processes arising from dynamical systems by evaluating a given observable along the orbits of the system. We focus on the extremal behaviour of th…
On Takens' Last Problem: tangencies and time averages near heteroclinic networks
Isabel S. Labouriau, Alexandre A. P. Rodrigues
We obtain a structurally stable family of smooth ordinary differential equations exhibiting heteroclinic tangencies for a dense subset of parameters. We use this to find vector fie…
Extremes and Recurrence in Dynamical Systems
Valerio Lucarini, Davide Faranda, Ana Cristina Moreira Freitas +6
This book provides a comprehensive introduction for the study of extreme events in the context of dynamical systems. The introduction provides a broad overview of the interdiscipli…
Global Saddles for Planar Maps
Begoña Alarcón, Sofia B. S. D. Castro, Isabel S. Labouriau
We study the dynamics of planar diffeomorphisms having a unique fixed point that is a hyperbolic local saddle. We obtain sufficient conditions under which the fixed point is a glob…
On statistical properties for equilibrium states of partially hyperbolic horseshoes
Vanessa Ramos, Jaqueline Siqueira
We derive some statistical properties for equilibrium states of partially hyperbolic horseshoes. We define a projection map associated to the horseshoe and prove a spectral gap for…
Semigroup actions of expanding maps
Maria Carvalho, Fagner B. Rodrigues, Paulo Varandas
We consider semigroups of Ruelle-expanding maps, parameterized by random walks on the free semigroup, with the aim of examining their complexity and exploring the relation between…
