Ne-integrabilnost in KAM izrek

Splošne dinamike zahtevnih hamiltonskih sistemov v večini primerov ne poznamo. KAM izrek nam kvalitativno opisuje orbite neke družine rešljivih sistemov, če sisteme rahlo perturbiramo. Pomaga nam pri razumevanju nerešljivih sistemov in pri poznavanju nekaterih lastnosti gibanja.

Non-integrability and the KAM theorem

A general solution to Hamiltonian dynamical systems is in most of the cases not known. The KAM theorem qualitatively describes the orbits of a family of solvable systems after a small perturbation is applied. It helps us to understand the dynamics of complex systems and predict some characteristics of the motion.
