Minimal sets in non-smooth dynamical systems

Abstract

In this project we study the existence of minimal invariant sets in non-smooth dynamical systems. In particular, we are interested in the existence of limit cycles and homoclinic cycles in dimensions $2$ and $3$.In dimension $2$ we focus on the existence of homoclinic cycles for non-smooth systems with two zones, considering the cases saddle-focus and saddle-center (real and virtual). We also want to study the existence of limit cycles for non-smooth dynamical systems with a circle as discontinuity manifold.In dimension $3$ we study the existence of limit cycles and homoclinic orbits in the special case of a model presenting two parallel $T$-singularities.
