On KAM theory

Part of the Applied Mathematical Sciences book series (AMS, volume 172)


As a motivation for this chapter we refer to the historical remarks of §2.2.5 and the references given there. The main question is to what extent a quasi-periodic subsystem, as defined in §2.2.3, is persistent under a small perturbation of the whole system, or say, under variation of parameters; see §3.2.
