The aim of KAM iteration is to eliminate the lower order terms of \(y\) in small perturbation \(f^{1}\) and \(f^{2}\) , which yields that we obtain a Gevrey normal form ( 5 ) of area preserving mappings, which ...

Web31 mar. 2009 · Abstract A Gevrey symplectic normal form of an analytic and more generally Gevrey smooth Hamiltonian near a Lagrangian invariant torus with a Diophantine vector of rotation is obtained. The normal form implies effective stability of the quasi-periodic motion near the torus.
