半平面上非线性薛定谔方程的Robin和Neumann问题

The Robin and Neumann problems for the nonlinear Schrödinger equation on the half-plane

A. Alexandrou Himonas, Dionyssios Mantzavinos

摘要:

本文研究了半平面上二维非线性薛定谔方程的初边值问题,初值在索伯列夫空间,边界点在适当的Bourgain空间.它建立了适定性的意义下的Hadamard通过利用明确的解决方案公式的强迫线性初边值问题通过Fokas的统一变换,和压缩映射参数。

英文摘要:

This work studies the initial-boundary value problem of the two-dimensional nonlinear Schrödinger equation on the half-plane with initial data in Sobolev spaces and Neumann or Robin boundary data in appropriate Bourgain spaces. It establishes well-posedness in the sense of Hadamard by utilizing the explicit solution formula for the forced linear initial-boundary value problem obtained via Fokas's unified transform, and a contraction mapping argument.
