本文研究了广义四阶薛定谔方程\[ i\partial _t u +\partial_x^4 u + \partial _x(|u| ^{2k}u)= 0,\quad u(0)=u_0,\]对于临界Sobolev空间$\dot {H}^{1/2-3/2k}$中的数据u 0。小的初始数据,我们得到的整体适定性的结果。我们的证明在很大程度上依赖于Kenig等人开发的方法。“通过收缩原理的广义Korteweg-de弗里斯方程的适定性和散射结果”,Commun。Pure Appl.Math.46(1993),527-620]。
Abstract We study the Cauchy problem for the generalised fourth-order Schrödinger equation \[ i\partial _t u +\partial _x^4 u + \partial _x (|u|^{2k}u)=0,\quad u(0)=u_0, \] for data u0 in critical Sobolev spaces $\dot {H}^{1/2-3/2k}$. With small initial data we obtain global well-posedness results. Our proof relies heavily on the method developed by Kenig et al. [‘Well-posedness and scattering results for the generalised Korteweg–de Vries equation via the contraction principle’, Commun. Pure Appl. Math.46 (1993), 527–620].
