利用适当的修正能量,我们研究了一般$2d$或$3d$紧致流形上的非线性薛定谔方程(NLS)的高阶Soblev范数的时间增长性。在$2d中,我们推广了以前只处理三次非线性项的结果,得到了任何高阶非线性项的多项式时间界。在$3D中,我们证明了三次NLS的解至多是指数增长的,而对于次三次NLS,我们得到了$H^2$-范数增长的多项式界。
Using suitable modified energies we study higher order Sobolev norms' growth in time for the nonlinear Schrodinger equation (NLS) on a generic $2d$ or $3d$ compact manifold. In $2d$ we extend earlier results that dealt only with cubic nonlinearities, and get polynomial in time bounds for any higher order nonlinearities. In $3d$, we prove that solutions to the cubic NLS grow at most exponentially, while for sub-cubic NLS we get polynomial bounds on the growth of the $H^2$-norm.
