二维反平方势nls的散射理论

Scattering theory for nls with inverse-square potential in 2d

Xiaofen Gao, Chengbin Xu

摘要:

本文研究了具有奇异位势的非线性薛定谔方程解的长时间行为。证明了二维$$iu_t+Δu-\frac{a u}{|x|^2}= -|u|^pu$$中具有平方反比势的径向非线性光学系统在基态以下的散射,当$2<p<\infty$和$a>0$。本文将文献[13,14,16]的结果推广到二维。关键点是Arora-Dodson-Murphy方法的修改版本[2]。

英文摘要:

In this paper, we study the long time behavior of the solution of nonlinear Schrödinger equation with a singular potential. We prove scattering below the ground state for the radial NLS with inverse-square potential in dimension two $$iu_t+Δu-\frac{a u}{|x|^2}= -|u|^pu$$ when $2<p<\infty$ and $a>0$. This work extends the result in [13, 14, 16] to dimension 2D. The key point is a modified version of Arora-Dodson-Murphy's approach [2].
