Dinâmica topológica do operador deslocamento com pesos
(Universidade Federal de São Carlos, 2020-04-20)
In the present work, we will do a study of linear dynamics of operators, focusing mainly on
the concepts of topological transitivity, hypercyclicity and chaoticity. At rst, we will deal
with non-linear dynamical systems ...
Três resultados de sistemas dinâmicos em dimensões baixas
(Universidade Federal de São Carlos, 2020-12-18)
This work contains three independent results that can be framed within the research
area named low-dimensional dynamics. The first result is a lower bound for the maximal
number of inseparable leaves of non-singular ...
The period function for some planar piecewise vector fields
(Universidade Federal de São Carlos, 2023-04-27)
In this work, we study the period function for fixed families of piecewise differential vector fields with a line of discontinuities. These systems, indistinctly called piecewise or nonsmooth, appear in several applications, ...
On the classification of two dimensional flows
(Universidade Federal de São Carlos, 2023-08-02)
Lawrence Markus, a well-known mathematician, published, in 1954, a strong result about classification of planar vector fields. Afterwards, Dean Arnold Neumann generalized such work for continuous flows, and the result ...
