Low-energy dynamics in generic potential fields: Hyperbolic periodic orbits and non-ergodicity

Dynamical Systems 2025-10-08 v1

Abstract

We prove that, on each low energy level, the natural Hamiltonian system defined by a generic smooth potential on T2\mathbf{T}^2 exhibits an arbitrarily high number of hyperbolic periodic orbits and a positive-measure set of invariant tori. Hence, quasi-periodic motion and hyperbolic behavior typically coexist in the low-energy dynamics of natural Hamiltonian systems with two degrees of freedom.
