Reducibility for a class of nonlinear quasi-periodic systems under Brjuno-Russmann's non-resonance conditions
Following Jorba and Simo's classical series, the work is to find the quasi-periodic solutions for analytic quasi-periodic non-linear systems under Bruno-Russmann's non-resonance condition. Moreover, the linear part systems are analytically reducible near such solutions. The tools utilized here are KAM methods.
