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, ...
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 ...
