Global dynamics of piecewise smooth dynamical systems

Abstract

The main aim of this project is to study global phenomena in piecewise smooth dynamical systems, continuing some recent works developed by the proponent. Among the main topics to be studied are (i) the existence of limit cycles in piecewise smooth dynamical systems defined on compact manifolds, (ii) the existence of Poincaré-Hopf-like theorems for pseudo-equilibria and (iii) the appearance of chaotic behavior in piecewise smooth systems, including Shilnikov-like phenomena.
