摘要:

本文考虑空间维中的离焦非线性薛定谔方程$d\geq 4$ .证明了若$u$是一个在临界索伯列夫空间中\emph{priori}有界的径向解,即$u\in L_t^\infty \dot{H}^{s_c}_x$,则$u$是全局的和分散的.在实践中,我们使用适合我们的设置的加权Eschhartz空间,这最终帮助我们解决了$d\geq 4$和$0<s_c<\f{1}{2}$情况下的问题。本文的结果将\cite [Comm. in PDE,40(2015),265-308]{M3}的工作扩展到更高的维度。

英文摘要:

In this paper, we consider the defocusing nonlinear Schrödinger equation in space dimensions $d\geq 4$. We prove that if $u$ is a radial solution which is \emph{priori} bounded in the critical Sobolev space, that is, $u\in L_t^\infty \dot{H}^{s_c}_x$, then $u$ is global and scatters. In practise, we use weighted Strichartz space adapted for our setting which ultimately helps us solve the problems in cases $d\geq 4$ and $0<s_c<\f{1}{2}$. The results in this paper extend the work of \cite[Comm. in PDEs, 40(2015), 265-308]{M3} to higher dimensions.
