Abstract

In this project we aim to study the existence and configuration of minimal sets in 3-dimensional piecewise smooth differential systems for two special classes of systems. Our main goal is to investigate the existence of codimension one manifolds filled up (or not) by periodic orbits after a non-smooth perturbation of a continuum of periodic orbits. Codimension two manifolds (limit cycles) will be also investigated. The methods involve geometric manipulation of the respective manifolds and eventually non-smooth versions of methods based on the Malkin's bifurcation funcion. (AU)
