A POSSIBLE MECHANISM FOR THE KAM TORI BREAKDOWN
(23K, LaTex)

ABSTRACT.  Inspired by the quantum field theory, a resummation is performed
in the Lindstedt series defining the KAM tori, and a possible mechanism
for universality of the tori breakdown is discussed.
This work is mostly based on a joint paper with G. Gallavotti.
