弱耦合非线性Schroedinger方程的爆破阈值

On the blow-up threshold for weakly coupled nonlinear Schroedinger equations

Luca Fanelli, Eugenio Montefusco

摘要:

研究了非线性光学中两个耦合非线性聚焦薛定谔方程组的柯西问题。我们讨论了何时解是整体的或在有限时间爆破。一些结果,在依赖的数据的问题,证明,特别是我们给一个界,依赖于耦合参数,爆破阈值。

英文摘要:

We study the Cauchy problem for a system of two coupled nonlinear focusing Schroedinger equations arising in nonlinear optics. We discuss when the solutions are global in time or blow-up in finite time. Some results, in dependence of the data of the problem, are proved; in particular we give a bound, depending on the coupling parameter, for the blow-up threshold.
