三维散焦立方薛定谔方程的整体适定性和散射

Global well-posedness and scattering of 3D defocusing, cubic Schrödinger equation

Jia Shen, Yifei Wu

摘要:

本文研究了三维散焦三次薛定谔方程的整体适定性和散射性。最近,Dodson [arXiv:2004.09618]研究了临界索伯列夫空间$\dot{W}^{11/7,7/6}$中的整体适定性.在本文中,我们的目的是表明,如果初始数据属于$\dot H^\frac12$,以保证局部存在,那么一些额外的弱空间,这是次临界,是足够的,以证明整体适定性。更精确地说,我们证明了,如果初始数据属于$\dot{H}^{1/2}\cap \dot{W}^{s,1}$为$12/13<s \leqslant 1$,那么相应的解决方案存在全局和分散。

英文摘要:

In this paper, we study the global well-posedness and scattering of 3D defocusing, cubic Schrödinger equation. Recently, Dodson [arXiv:2004.09618] studied the global well-posedness in a critical Sobolev space $\dot{W}^{11/7,7/6}$. In this paper, we aim to show that if the initial data belongs to $\dot H^\frac12$ to guarantee the local existence, then some extra weak space which is subcritical, is sufficient to prove the global well-posedness. More precisely, we prove that if the initial data belongs to $\dot{H}^{1/2}\cap \dot{W}^{s,1}$ for $12/13<s \leqslant 1$, then the corresponding solution exists globally and scatters.
