关于一维三次NLS方程在射线上的Dirichlet到Neumann问题;零初始值

On the Dirichlet to Neumann Problem for the 1-dimensional Cubic NLS equation on the Half-Line; Zero Initial Data

Dimitra C. Antonopoulou, Spyridon Kamvissis

摘要:

1维“完全可积”方程的初边值问题可以通过逆散射方法的扩展来解决,这是由于Fokas和他的合作者。这种方法的一个重要特点是,它需要更多的边界数据的值比给定的一个适定问题。在三次NLS的情况下,知识的Dirichet数据足以使问题适定,但Fokas方法还需要知识的诺依曼数据的值。因此,在应用“Fokas变换”之前,研究Dirichlet到Neumann映射是必要的。在本文中,我们提供了一个严格的研究这个地图的一大类衰减狄利克雷数据。我们表明,诺依曼数据也充分衰减,因此,可以应用Fokas方法。为了简单起见,我们在这里考虑零初始数据的情况。随后将提供一份附录,讨论非零初始数据的情况。

英文摘要:

Initial-boundary value problems for 1-dimensional `completely integrable' equations can be solved via an extension of the inverse scattering method, which is due to Fokas and his collaborators. A crucial feature of this method is that it requires the values of more boundary data than given for a well-posed problem. In the case of cubic NLS, knowledge of the Dirichet data suffices to make the problem well-posed but the Fokas method also requires knowledge of the values of Neumann data. The study of the Dirichlet to Neumann map is thus necessary before the application of the `Fokas transform'. In this paper, we provide a rigorous study of this map for a large class of decaying Dirichlet data. We show that the Neumann data are also sufficiently decaying and hence that the Fokas method can be applied. For simplicity we considered here the case of zero initial data. An addendum will follow, discussing the case of non-zero initial data.
