A version of Kac's lemma on first return times for suspension flows
Paulo Varandas
In this article we study the mean return times to a given set for suspension flows. In the discrete time setting, this corresponds to the classical version of Kac's lemma \cite{K}…
Multifractal analysis of the irregular set for almost-additive sequences via large deviations
Thiago Bomfim, Paulo Varandas
In this paper we introduce a notion of free energy and large deviations rate function for asymptotically additive sequences of potentials via an approximation method by families of…
Statistical stability for multidimensional piecewise expanding maps
Jose F. Alves, Antonio Pumarino, Enrique Vigil
We present sufficient conditions for the (strong) statistical stability of some classes of multidimensional piecewise expanding maps. As a consequence we get that a certain natural…
Invariant probability measures and non-wandering sets for impulsive semiflows
Jose F. Alves, Maria Carvalho
We consider impulsive dynamical systems defined on compact metric spaces and their respective impulsive semiflows. We establish sufficient conditions for the existence of probabili…
A dichotomy in area-preserving reversible maps
Mario Bessa, Alexandre Rodrigues
In this paper we study R-reversible area-preserving maps f on a two-dimensional Riemannian closed manifold M, i.e. diffeomorphisms f such that Ro f=f^{-1}o R where R is an isometri…
SRB measures for partially hyperbolic systems whose central direction is weakly expanding
Jose F. Alves, C. L. Dias, S. Luzzatto +1
We consider partially hyperbolic \( C^{1+} \) diffeomorphisms of compact Riemannian manifolds of arbitrary dimension which admit a partially hyperbolic tangent bundle decomposition…
Discrete dynamical systems from mutation-periodic quivers: examples and reduction
Inês Cruz, M. Esmeralda Sousa-Dias
Several new mutation-periodic quivers of period higher than 1 are introduced as well as the associated discrete dynamical systems. The reduction of these systems is developed using…
Dense heteroclinic tangencies near a Bykov cycle
Isabel S. Labouriau, Alexandre A. P. Rodrigues
This article presents a mechanism for the coexistence of hyperbolic and non-hyperbolic dynamics arising in a neighbourhood of a Bykov cycle where trajectories turn in opposite dire…
Generic area-preserving reversible diffeomorphisms
Mário Bessa, Maria Carvalho, Alexandre Rodrigues
Let M be a surface and R an involution in M whose set of fixed points is a submanifold with dimension 1 and such that R is an isometry. We will show that there is a residual subset…
Speed of convergence for laws of rare events and escape rates
Ana Cristina Moreira Freitas, Jorge Milhazes Freitas, Mike Todd
We obtain error terms on the rate of convergence to Extreme Value Laws for a general class of weakly dependent stochastic processes. The dependence of the error terms on the `time'…
Stability in simple heteroclinic networks in
Sofia B. S. D. Castro, Alexander Lohse
We describe all heteroclinic networks in made of simple heteroclinic cycles of types or , with at least one common connecting trajectory. For networks made of…
