具有吸引δ势的1 $d$ NLS小孤波的稳定性

Stability of small solitary waves for the 1$d$ NLS with an attractive delta potential

Satoshi Masaki, Jason Murphy, Jun-ichi Segata

摘要:

研究了具有吸引力δ势的一维非线性薛定谔方程的初值问题.我们发现,对于足够小的初始数据,相应的全球解决方案分解成一个小的孤波加上一个辐射项,衰减和散射为$t\to\infty$。特别地,我们建立了小孤波族的渐近稳定性。

英文摘要:

We consider the initial-value problem for the one-dimensional nonlinear Schrödinger equation in the presence of an attractive delta potential. We show that for sufficiently small initial data, the corresponding global solution decomposes into a small solitary wave plus a radiation term that decays and scatters as $t\to\infty$. In particular, we establish the asymptotic stability of the family of small solitary waves.
