Twistless KAM tori.


A selfcontained proof of the KAM theorem in the Thirring model is discussed. I shall particularize the Eliasson method, E], for KAM tori to a special model, of great interest, whose relevance for the KAM problem was pointed out by Thirring, T] (see G] for a short discussion of the model). The idea of exposing Eliasson's method through simple particular… (More)
