Exponentially small estimates for KAM theorem near an elliptic equilibrium point
(1997)
Article
Accés obertWe give a precise statement of KAM theorem for a Hamiltonian system in a neighborhood of an elliptic equilibrium point. If the frequencies of the elliptic point satisfy a Diophantine condition, with exponent $\tau$, and ... -
Invariant curves for area preserving maps
(Universitat Politècnica de Catalunya, 2019-07)
Projecte Final de Màster Oficial
Accés obertThis work aims to present tool of this approach is the so-called parameterization method, that produces a Newton-like iterative method to solve the invariance equation for an invariant torus, and the KAM theorem is a result ... -
Teoria Kam Sin Coordenadas Accion-Angulo
(2001)
Article
Accés obertThe classical KAM methods, strongly supported on the use of canonical trans- formations in the action-angle context, are not effcient to be applied to a wide range of systems in which the Hamiltonian is known (for instance) ...
