Hausdorff Dimension and Flexibility for Attractors of Non-Uniformly Hyperbolic Flows

Elias Rego, Paulo Varandas

We study the Hausdorff dimension of attracting sets of three-dimensional flows whose one-dimensional quotient dynamics is non-uniformly expanding. Our main assumption is that the q…

Good inducing schemes for uniformly hyperbolic flows, and applications to exponential decay of correlations

Ian Melbourne, Paulo Varandas

Given an Axiom A attractor for a flow (), we construct a countable Markov extension with exponential return times in such a way that the inducing set is a smoothly e…

Phase transitions for surface diffeomorphisms

Thiago Bomfim, Paulo Varandas

In this paper we consider surface diffeomorphisms and study the existence of phase transitions, here expressed by the non-analiticity of the pressure function associated to s…

Topological and metric emergence of continuous maps

Maria Carvalho, Fagner B. Rodrigues, Paulo Varandas

We prove that the homeomorphisms of a compact manifold with dimension one have zero topological emergence, whereas in dimension greater than one the topological emergence of a C^0-…

Quenched decay of correlations for nonuniformly hyperbolic random maps with an ergodic driving system

José F. Alves, Wael Bahsoun, Marks Ruziboev +1

In this article we study random tower maps driven by an ergodic automorphism. We prove quenched exponential correlations decay for tower maps admitting exponential tails. Our techn…

Thermodynamic formalism for expanding measures

Vilton Pinheiro, Paulo Varandas

In this paper we study the thermodynamic formalism of strongly transitive endomorphisms , focusing on the set all expanding measures. In case is a non-flat map defi…
