Description: |
Classical Kolmogrov-Arnold-Moser theory studies stability problem for invariant tori for nearly integrable dynamical systems. This theory has been developed beyond nearly integrable systems. I will explain basic concepts and results of the classical KAM theorem. Then I will state a KAM theorem for Presymplectic dynamical systems which has a different approach to the problem of the stability of invariant tori than the classical KAM. Starting with an approximate invariant torus, I will introduce an algorithm to find an invariant torus nearby.
