Title: Majorant series convergence for twistless KAM tori

Abstract: A selfcontained proof of the KAM theorem in the
Thirring model is discussed, completely relaxing
the ``strong diophantine property'' hypothesis used in previous papers.

In Ergodic theory and dynamical systems, {\bf 15}, p.  857--869, 1995

Keywords: KAM, invariant tori, classical mechanics, 
perturbation theory, chaos
