Extension of hypercyclic and frequently hypercyclic subspaces

Felipe Carvalho Silva, Geivison Ribeiro, Régis Varão

We focus on the existence of large linear structures within the sets of hypercyclic and frequently hypercyclic vectors. For operators satisfying Kitai's Criterion or the Freque…

Dynamics of composition operators induced by odometers

Udayan B. Darji, Daniel Gomes, Régis Varão

We study the linear dynamics of composition operators induced by measurable transformations on finite measure spaces, with particular emphasis on operators induced by odometers. Ou…

Anosov actions: minimality of foliations or suspension action

Rodrigo R. Lopes, Carlos Maquera, Régis Varão

We prove that an Anosov action of over a compact manifold transitive on regular sub-cones satisfies the dichotomy: each stable and unstable leaf is dense or the…

Entropy for compact operators and results on entropy and specification

Paulo Lupatini, Felipe Silva, Régis Varão

We investigate the topological entropy of operators. More precisely, in the Banach space setting, we show that compact operators have finite entropy, which depends solely on their…

Folding and Metric Entropies for Extended Shifts

Neemias Martins, Pedro G. Mattos, Régis Varão

In this paper we calculate the metric and folding entropies for a family of non-invertible symbolic dynamical systems which generalizes the standard bilateral…

The Orbit Space Approach for Piecewise Smooth Vector Fields

Otávio M. L. Gomide, Pedro G. Mattos, Régis Varão

In this work we develop a well-defined theory of orbit spaces for piecewise smooth vector fields (PSVFs). This approach is inspired by the techniques already used in the study of e…
