报告摘要：
We construct time quasi-periodic solutions to the nonlinear Klein-Gordon equation with polynomial nonlinear terms on the two dimensional torus: (∂^2 u)/(∂t^2 ) −∆u+u+u^(p+1) =0.
To our knowledge, this is the first such result to the Klein-Gordon equation above dimension one. The analysis explores in an essential way the submodule structure on a dual Fourier lattice.
