加权索伯列夫空间中具有初值的NLS方程解的长时间渐近性

Long-time asymptotics for solutions of the NLS equation with initial data in a weighted Sobolev space

P. Deift, X. Zhou

摘要:

在初始数据位于加权索伯列夫空间的假设下,计算了NLS方程解的长时间渐近性。在早期的工作中(例如见[DZ1],[DIZ]),初始数据需要高阶衰减和平滑。本文的方法是[DZ 1]的最速下降方法的进一步发展,并用振荡抵消代替了[DZ 1]中的某些绝对型估计。

英文摘要:

The authors compute the long-time asymptotics for solutions of the NLS equation just under the assumption that the initial data lies in a weighted Sobolev space. In earlier work (see e.g. [DZ1],[DIZ]) high orders of decay and smoothness are required for the initial data. The method here is a further development of the steepest descent method of [DZ1], and replaces certain absolute type estimates in [DZ1] with cancellation from oscillations.
