Is there switching without suspended horseshoes?
Alexandre Rodrigues
In general, infinite switching behaviour near networks is associated with the existence of suspended horseshoes. Trajectories that realize switching lie within these transitive set…
Limit cycles for a class of equivariant systems without infinite equilibria
Isabel S. Labouriau, Adrian C. Murza
We analyze the dynamics of a class of -equivariant differential equations on the plane, depending on 4 real parameters. This study is the generalisation to $\mathb…
On Equilibrium States for Partially Hyperbolic Horseshoes
Isabel Rios, Jaqueline Siqueira
We prove existence and uniqueness of equilibrium states for a family of partially hyperbolic systems, with respect to Holder continuous potentials with small variation. The family…
Clustering of extreme events created by multiple correlated maxima
Davide Azevedo, Ana Cristina Moreira Freitas, Jorge Milhazes Freitas +1
We consider stochastic processes arising from dynamical systems by evaluating an observable function along the orbits of the system. The novelty is that we will consider observable…
(Semi)continuity of the entropy of Sinai probability measures for partially hyperbolic diffeomorphisms
M. Carvalho, P. Varandas
We establish sufficient conditions for the upper semicontinuity and the continuity of the entropy of Sinai probability measures invariant by partially hyperbolic diffeomorphisms an…
Construction of heteroclinic networks in
Alexander Lohse, Sofia B. S. D. Castro
We study heteroclinic networks in , made of a certain type of simple robust heteroclinic cycle. In simple cycles all the connections are of saddle-sink type in two-di…
Rare Events for the Manneville-Pomeau map
Ana Cristina Moreira Freitas, Jorge Milhazes Freitas, Mike Todd +1
We prove a dichotomy for Manneville-Pomeau maps : given any point , either the Rare Events Point Processes (REPP), counting the number of exceedances…
Dynamics of the birational maps arising from and quivers
Inês Cruz, Helena Mena-Matos, M. Esmeralda Sousa-Dias
The dynamics of the maps associated to and quivers is studied in detail. We show that the corresponding reduced symplectic maps are conjugate to globally periodic maps…
Specification properties and thermodynamical properties of semigroup actions
Fagner B. Rodrigues, Paulo Varandas
In the present paper we study the thermodynamical properties of finitely generated continuous subgroup actions. We address a notion of topological entropy and pressure functions th…
Specification and partial hyperbolicity for flows
Naoya Sumi, Paulo Varandas, Kenichiro Yamamoto
In this article we prove that if a flow exhibits a partially hyperbolic attractor and it has two periodic saddles with different indices, and the stable index of one of them coinci…
Extremal dichotomy for uniformly hyperbolic systems
Maria Carvalho, Ana Cristina Moreira Freitas, Jorge Milhazes Freitas +2
We consider the extreme value theory of a hyperbolic toral automorphism showing that if a Hölder observation which is a function of a Euclide…
Extreme Value Theory for Piecewise Contracting Maps with Randomly Applied Stochastic Perturbations
D. Faranda, J. -M. Freitas, P. Guiraud +1
We consider globally invertible and piecewise contracting maps in higher dimensions and we perturb them with a particular kind of noise introduced by Lasota and Mackey. We got rand…
