Abstract
We describe a method to study the existence of
whiskered quasi-periodic solutions in Hamiltonian
systems.
The method applies to finite dimensional systems
and also to lattice systems and to PDE's including
some ill posed ones.
In coupled map lattices, we can also
construct solutions of infinitely many frequencies
which do not vanish asymptotically.
期刊介绍：
Electronic Research Archive (ERA), formerly known as Electronic Research Announcements in Mathematical Sciences, rapidly publishes original and expository full-length articles of significant advances in all branches of mathematics. All articles should be designed to communicate their contents to a broad mathematical audience and must meet high standards for mathematical content and clarity. After review and acceptance, articles enter production for immediate publication.
ERA is the continuation of Electronic Research Announcements of the AMS published by the American Mathematical Society, 1995—2007
