Renormalization and Diophantine invariant 
KAM tori of Hamiltonian flows
(53K, Revtex4)

ABSTRACT.  We apply a renormalization scheme to construct invariant tori with 
Diophantine frequency vectors for two degree-of-freedom, 
near-integrable analytic Hamiltonians. We prove that the tori are 
analytic functions.
