 报告简介:

We will survey the recent evelopments about the stability of the solitary waves for the (generalized) derivative Schrodinger equation. We firstly show the existence/nonexistence of traveling waves for NLS with derivative (DNLS) by the structure analysis, ODE argument and the variational argument. Secondly, we consider the orbital stability of the solitary waves for the derivative Schrodinger equation in the energy space. Last, we will show the orbital instability of the solitary waves for the generalized derivative Schrodinger equation in the degenerate case. They are joint works with Prof. Changxing Miao and Xingdong Tang.
