带势非线性薛定谔方程的非径向散射理论

Non-radial scattering theory for nonlinear Schrödinger equations with potential

Van Duong Dinh

摘要:

考虑一类具有势\[ i\partial_t u +Δu - Vu = \pm |u|^αu, \quad (t,x) \in \mathbb{R} \times \mathbb{R}^3, \]的非线性薛定谔方程,其中$\frac{4}{3}<α<4$和$V$是Kato型势.利用Dodson-Murphy [Math. Res. Lett.]的思想,建立了非径向初值方程的散射准则。25(6):1805- 1825]。因此,我们证明了能量散射的聚焦问题的数据低于基态阈值。我们的结果推广了Hong [Commun.纯应用。肛门。15(5):1571--1601]和Hamano-Ikeda [J. Evol.当量ag 2019年]。我们还研究了在基态阈值的数据聚焦问题的全局解的长时间动态。

英文摘要:

We consider a class of nonlinear Schrödinger equations with potential \[ i\partial_t u +Δu - Vu = \pm |u|^αu, \quad (t,x) \in \mathbb{R} \times \mathbb{R}^3, \] where $\frac{4}{3}<α<4$ and $V$ is a Kato-type potential. We establish a scattering criterion for the equation with non-radial initial data using the ideas of Dodson-Murphy [Math. Res. Lett. 25(6):1805--1825]. As a consequence, we prove the energy scattering for the focusing problem with data below the ground state threshold. Our result extends the recent works of Hong [Commun. Pure Appl. Anal. 15(5):1571--1601] and Hamano-Ikeda [J. Evol. Equ. 2019]. We also study long time dynamics of global solutions to the focusing problem with data at the ground state threshold.
