Abstract

In this project we study the existence of limit cycles for two kind of dynamical systems: perturbations of piecewise smooth systems in R^n possessing a invariant compact submanifold filled by periodic orbits and also linear piecewise smooth dynamical systems on manifolds of the form M= R^n x ( S^k)^m. The case m=0, in particular when n2, has been exhaustively studied in the last years, so we consider n different from 0 and m,k\geq 1. We will show that the study of limit cycles for non-planar piecewise smooth vector fields is a very active research topic with very interesting results, motivating the student for more advanced studies in the area of piecewise smooth dynamical systems.
