摘要 讨论了一维空间中带调和势的非线性Schr dinger方程iφt =- φxx +x2 φ- φ|φ|4,t≥ 0 ,x∈R的Cauchy问题 .在得到其局部适定性的基础上 ,利用一类特殊的变分方法和质量与能量守恒律 ,获得了其整体解存在的一个L2 控制条件 ,并运用待定求解法以及matlab数值技术和有界性定理 ,给出了该L2 In this paper, we consider the Cauchy problem of nonlinear Schrdinger equation with harmonic potentials in one dimension.  i φ t=-φ xx +x 2φ-φ|φ| 4, t≥0, x∈R. On the basis of the local well posed theorem, we obtain the L 2 control condition of the global existence by using a class of special variantional approach along with mass and energy conservation law moreoever, applying method of undetermined multipliers, matlab numerical technique and boundedness principle, we show the sharp numerical representation of the L 2 control condition.
