关于具有非类属势的$1$ d三次NLS

On the $1$d cubic NLS with a non-generic potential

Gong Chen, Fabio Pusateri

摘要:

我们考虑了具有非一般性外势$V$的$1d$立方非线性薛定谔方程.在不对数据做任何奇偶性假设的情况下,但假设相关薛定谔算子的零能量共振是奇数或偶数,我们证明了小解的全局时间定量界和渐近性。首先,我们使用一个简单的修改的基础上的扭曲的傅里叶变换(dFT),以解决(可能的)不连续性在零能量由于存在的共振和对称性的解决方案。然后,我们使用(修改后的)非线性谱分布的低频结构的精细分析,并采用平滑估计在设置非通用的潜力。

英文摘要:

We consider the $1d$ cubic nonlinear Schrödinger equation with an external potential $V$ that is non-generic. Without making any parity assumption on the data, but assuming that the zero energy resonance of the associated Schrödinger operator is either odd or even, we prove global-in-time quantitative bounds and asymptotics for small solutions. First, we use a simple modification of the basis for the distorted Fourier transform (dFT) to resolve the (possible) discontinuity at zero energy due to the presence of a resonance and the absence of symmetry of the solution. We then use a refined analysis of the low frequency structure of the (modified) nonlinear spectral distribution, and employ smoothing estimates in the setting of non-generic potentials.
