一个二维非线性Schrdinger方程的整体适定性

Global well-posedness of a 2D nonlinear Schrdinger equation

利用高低频技术证明了当初值属于Hs(R2),s>1617时二维五次非线性Schr dinger方程的整体适定性.

By using the high\|low frequency technique,it can be proved that the 2D quintic nonlinear Schrdinger equation is globally well\|posed for data in Sobolev space H\+s(R\+2),where s>16/17.
