Higher-derivative harmonic oscillators: stability of classical dynamics and adiabatic invariants
Abstract The status of classical stability in higher-derivative systems is still subject to discussions. In this note, we argue that, contrary to general belief, many higher-derivative systems are classically stable. The main tool to see this property are Nekhoroshev’s estimates relying on the actio...
