非线性Schroedinger方程多孤子解的渐近稳定性

Asymptotic stability of multi-soliton solutions for nonlinear Schroedinger eqations

G. Perelman

摘要:

本文考虑初始值接近于N个解耦孤子之和的非线性Schroedinger方程的Cauchy问题。在对单孤子线性化的谱结构作适当假设的情况下,我们证明了在大的时间内,解的渐近性是由参数稍有修改的孤子和一个小的色散项所给出的。

英文摘要:

We consider the Cauchy problem for the nonlinear Schroedinger eqiation with initial data close to a sum of N decoupled solitons. Under some suitable assumptions on the spectral structure of the one soliton linearizations we prove that for large time the asymptotics of the solution is given by a sum of solitons with slightly modified parameters and a small dispersive term.
