1. Tangências homoclínicas, entropia e medidas de SRB / Homoclinic tangencies, entropy and SRB measure
We study the effect of a homoclinic tangency in the variation of the topological entropy. We prove that a diffeomorphism with a homoclinic tangency associated to a basic hyperbolic set with maximal entropy is a point of entropy variation in the C POT THE INFINITEtopology. We also discuss variational problem in C POT.1topology and we show an example of discon

2. Orbitas homoclinicas em sistemas reversiveis / Homoclinic orbits in reversible systems
In this work we deal with the dynamics of a generic one-parameter family INT . IND. mu, PERTENCE (-e, e), of reversible vector fields defined in R POT. 4 . More specifically, we assume that INT IND. o (0) = 0, the eigenvalues of D INT IND. o (0) are real and given by + ou - 1, + ou - gama with gama >1 and the unstable manifolds of 0, WU POT. ipsilon (0) poss

3. Analysis of attracting and non-attracting chaotic sets in low and high-dimensional dynamical systems: application to the dynamics of plasma waves in the sun-earth connection / Análise de conjuntos caóticos atrativos e não atrativos em sistemas dinâmicos de baixa e alta dimensão: aplicação para a dinâmica de ondas de plasma na conexão sol - terra
In this work we present a numerical study on the interaction between chaotic attractors and nonattracting chaotic sets in mathematical models that describe the nonlinear dynamics of plasma waves in the Sun-Earth connection. The work is divided in two parts. In the first part we analyze a low-dimensional dynamical system describing stationary Alfv´en waves m
