E. De Simone, A. Kupiainen

We give an elementary proof of the analytic KAM theorem by reducing it to a Picard iteration of a PDE with quadratic nonlinearity, the so called Polchinski renormalization group eq…

A Renormalization Proof of the KAM Theorem for Non-Analytic Perturbations

Emiliano De Simone

We shall use a Renormalization Group (RG) scheme in order to prove the classical KAM result in the case of a non-analytic perturbation (the latter will be assumed to have continuou…
