具有平方反比势的非线性薛定谔方程有限时间爆破解的质量集中和特征

Mass concentration and characterization of finite time blow-up solutions for the nonlinear Schrödinger equation with inverse-square potential

Abdelwahab Bensouilah, Van Duong Dinh

摘要:

本文考虑具有平方反比势$$ i \partial_t u +Δu + c|x|^{-2} u = -|u|^{\frac{4}{d}} u, \quad u(0) = u_0, \quad (t,x) \in \mathbb{R}^+ \times \mathbb{R}^d, $$的$L^2$ -临界NLS,其中$d\geq 3$和$c\ne 0$满足$c<λ(d) := \left(\frac{d-2}{2}\right)^2$ .利用精化紧性引理,将第一作者在[Bensouilah]中建立的吸引情形下有限时间爆破解的质量集中推广到$c<λ(d)$ .利用一个简单而简短的极限轮廓定理,我们得到了与Csobo和Genoud在[CsoboGenoud]中对$0<c<λ(d)$得到的相同的分类结果.它还使我们能够将分类扩展到$c<λ(d)$。

英文摘要:

We consider the $L^2$-critical NLS with inverse-square potential $$ i \partial_t u +Δu + c|x|^{-2} u = -|u|^{\frac{4}{d}} u, \quad u(0) = u_0, \quad (t,x) \in \mathbb{R}^+ \times \mathbb{R}^d, $$ where $d\geq 3$ and $c\ne 0$ satisfies $c<λ(d) := \left(\frac{d-2}{2}\right)^2$. Using a refined compactness lemma, we extend the mass concentration of finite time blow-up solutions established in the attractive case by the first author in [Bensouilah] to $c<λ(d)$. By means of a simple and short limiting profile theorem, we get the same classification result obtained by Csobo and Genoud in [CsoboGenoud] for $0<c<λ(d)$. It also enables us to extend the classification to $c<λ(d)$.
