积空间上三次薛定谔方程的修正散射:非共振情形

Modified scattering for the cubic Schr{ö}dinger equation on product spaces: the nonresonant case

Benoît Grébert, Eric Paturel, Laurent Thomann

摘要:

我们考虑空间域$\mathbb{R}\times \mathbb{T}^d$上的三次非线性薛定谔方程,用卷积势对其进行扰动.利用最近的技术的Hani-Pausader-Tzvetkov-Visciglia,我们证明了修改的散射结果和构造修改的波算子,在一般的假设下的潜力。特别是,这使我们能够证明,这个非共振立方NLS的小解的Sobolev范数是渐近常数。

英文摘要:

We consider the cubic nonlinear Schr{ö}dinger equation on the spatial domain $\mathbb{R}\times \mathbb{T}^d$, and we perturb it with a convolution potential. Using recent techniques of Hani-Pausader-Tzvetkov-Visciglia, we prove a modified scattering result and construct modified wave operators, under generic assumptions on the potential. In particular, this enables us to prove that the Sobolev norms of small solutions of this nonresonant cubic NLS are asymptotically constant.
