非解析扰动下KAM定理的重整化证明

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

Emiliano De Simone

摘要:

我们将使用一个重整化群(RG)的计划,以证明经典的KAM结果的情况下,非解析扰动(后者将被假定为有连续的导数,直到足够大的订单)。我们将着手解决一系列问题,其中的扰动是原问题的解析近似。最后,我们将证明近似解的序列将收敛到原问题的可微解。

英文摘要:

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 continuous derivatives up to a sufficiently large order). We shall proceed by solving a sequence of problems in which the perturbations are analytic approximations of the original one. We shall finally show that the sequence of the approximate solutions will converge to a differentiable solution of the original problem.
