旋转超临界NLS驻波解的整体适定性、爆破和稳定性

Global well-posedness, blow-up and stability of standing waves for supercritical NLS with rotation

Alex H. Ardila, Hichem Hajaiej

摘要:

考虑带转动的聚焦质量超临界非线性薛定谔方程\begin{equation*} iu_{t}=-\frac{1}{2}Δu+\frac{1}{2}V(x)u-|u|^{p-1}u+L_Ωu,\quad (x,t)\in \mathbb{R}^{N}\times\mathbb{R}, \end{equation*},其中$N=2$或$3$,$V(x)$为各向异性调和势.这里$L_Ω$是量子力学角动量算符。我们建立的整体存在和爆破的能量空间的条件。此外,我们证明了在一定条件下的旋转和波的频率的驻波强不稳定性。最后,我们通过考虑适当的局部极小化问题,构造了轨道稳定的驻波解。这些结果得到的非线性是$L^{2}$ -超临界。

英文摘要:

We consider the focusing mass supercritical nonlinear Schrödinger equation with rotation \begin{equation*} iu_{t}=-\frac{1}{2}Δu+\frac{1}{2}V(x)u-|u|^{p-1}u+L_Ωu,\quad (x,t)\in \mathbb{R}^{N}\times\mathbb{R}, \end{equation*} where $N=2$ or $3$ and $V(x)$ is an anisotropic harmonic potential. Here $L_Ω$ is the quantum mechanical angular momentum operator. We establish conditions for global existence and blow-up in the energy space. Moreover, we prove strong instability of standing waves under certain conditions on the rotation and the frequency of the wave. Finally, we construct orbitally stable standing waves solutions by considering a suitable local minimization problem. Those results are obtained for nonlinearities which are $L^{2}$-supercritical.
