关于双曲空间上NLS的高低法

On the high-low method for NLS on the hyperbolic space

Gigliola Staffilani, Xueying Yu

摘要:

本文首先证明了二维双曲空间上具有径向初值的三次散焦非线性薛定谔方程在$H^s(\mathbb{H}^2)$中是整体适定的,当$s > \frac{3}{4}$ .然后将结果推广到$p>3$阶非线性方程.在双曲情形下推广了Bourgain的高低法,并利用第一作者和Ionescu证明的Morawetz型估计证明了这一结果。

英文摘要:

In this paper, we first prove that the cubic, defocusing nonlinear Schrödinger equation on the two dimensional hyperbolic space with radial initial data in $H^s(\mathbb{H}^2)$ is globally well-posed and scatters when $s > \frac{3}{4}$. Then we extend the result to nonlineraities of order $p>3$. The result is proved by extending the high-low method of Bourgain in the hyperbolic setting and by using a Morawetz type estimate proved by the first author and Ionescu.
