一维非线性薛定谔方程的长时间动力学

Long time dynamics for the one dimensional non linear Schrödinger equation

Nicolas Burq, Laurent Thomann, Nikolay Tzvetkov

摘要:

本文首先给出了带调和势的非线性薛定谔方程的Gibbs测度的构造。然后,我们证明了相应的柯西问题是全局适定的粗糙初始条件的统计集(支持的措施)。最后,我们证明了吉布斯测度确实是不变的方程的流动。作为我们分析的副产品,我们给出了$L^2$临界和超临界NLS(无调和势)的整体适定性和散射结果。

英文摘要:

In this article, we first present the construction of Gibbs measures associated to nonlinear Schrödinger equations with harmonic potential. Then we show that the corresponding Cauchy problem is globally well-posed for rough initial conditions in a statistical set (the support of the measures). Finally, we prove that the Gibbs measures are indeed invariant by the flow of the equation. As a byproduct of our analysis, we give a global well-posedness and scattering result for the $L^2$ critical and super-critical NLS (without harmonic potential).
