Homoclinic Theorems for piecewise smooth vector fields

Dynamical Systems 2026-07-10 v1

Abstract

In this paper we provide extensions of the Birkhoff-Smale Homoclinic Theorem and the λ\lambda-Lemma for piecewise smooth vector fields free of sliding motion. We prove that if the vector field is TT-periodic in its independent variable and has a transverse homoclinic point, then its time-TT-map is conjugated with a Bernoulli Shift and thus the vector field is chaotic. The Bernoulli Shifts considered here may have any finite number of symbols, or countably infinite many.
