报告摘要: In this talk, an infinite dimensional KAM theorem with multiple normal frequencies is established under qualitative non-degenerate conditions. This is an extension of the degenerate KAM theorem with simple normal frequencies by Bambusi, Berti and Magistrelli and the authors. As applications, for higher dimensional nonlinear Schrodinger equation with periodic boundary conditions, quasi-periodic solutions of small amplitude and quasi-periodic solutions around plane wave are obtained.
