Title: Attracting invariant tori and analytic conjugacies
Author: H. Koch
Abstract:   We consider the problem of conjugating a flow on T2×R to an "integrable" flow q'=ω and p'=cp, if possible, with c≠0. Our emphasis is on a constructive approach, using a KAM type iteration and analyticity. An application to the periodically forced Van der Pol oscillator is given.
