Singular KAM theory for convex Hamiltonian systems

Santiago Barbieri, Luca Biasco, Luigi Chierchia +1

In this note, we briefly discuss how singular KAM Theory - which was worked out in a previous work by L.B. and L.C. for the mechanical case - can b…

Singular KAM Theory

Luca Biasco, Luigi Chierchia

The question of the total measure of invariant tori in analytic, nearly--integrable Hamiltonian systems is considered. In 1985, Arnol'd, Kozlov and Neishtadt, in the Encyclopaedia…

Global properties of generic real-analytic nearly-integrable Hamiltonian systems

Luca Biasco, Luigi Chierchia

We introduce a new class of generic real analytic potentials on and study global analytic properties of natural nearly-integrable Hamiltonians $\fra…

Complex Arnol'd-Liouville maps

Luca Biasco, Luigi Chierchia

We discuss the holomorphic properties of the complex continuation of the classical Arnol'd-Liouville action-angle variables for real analytic 1 degree--of--freedom Hamiltonian syst…

Quasi-periodic motions in generic nearly-integrable mechanical systems

Luca Biasco, Luigi Chierchia

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 invarian…

V.I. Arnold's "Global" KAM Theorem and geometric measure estimates

L. Chierchia, C. E. Koudjinan

This paper continues the discussion started in [CK19] concerning Arnold's legacy on classical KAM theory and (some of) its modern developments. We prove a detailed and explicit `gl…
