Title: Methods in the theory of quasi periodic motions

Abstract: 
Recent results on the theory of the Hamilton--Jacobi 
equation and the regularity of their solutions, in spite 
of the non regularity of the data, are discussed, with 
attention to the cancellation mechanisms that make 
regularity possible.

Keywords: KAM, Quasiperiodic Schroedinger, Implicit 
functions
