Quasi-periodic motions in generic nearly-integrable mechanical systems

Abstract

In this note we present and briefly discuss results, which include as a particular case the theorem announced in [L. Biasco, and L. Chierchia. On the measure of Lagrangian invariant tori in nearly-integrable mechanical systems. Atti Accad. Naz. Lincei Rend. Lincei Mat. Appl. 26 (2015), 1-10], concerning the typical behaviour of nearly-integrable mechanical systems with generic analytic potentials.
