二维Zakharov方程组的整体粗糙解

Global rough solutions for the Zakharov system in two spatial dimensions

Hartmut Pecher

摘要:

我们证明了改进的全局适定性结果Zakharov系统在两个空间维度与最小的正则性假设的数据。特别是我们能够允许薛定谔和波动数据,它们分别不属于H^1和L^2,因此具有无穷大的能量。证明使用了最初由Colliander,Keel,Staffilani,Takaoka和Tao发起的改进的I-方法以及Bejenaru,Herr,Holmer和Tataru的双线性估计。并给出了解的多项式增长界。

英文摘要:

We show an improved global well-posedness result for the Zakharov system in two space dimensions with minimal regularity assumptions for the data. Especially we are able to allow Schroedinger and wave data, which do not belong to H^1 and L^2, respectively, thus with infinite energy. The proof uses a refined I-method originally initiated by Colliander, Keel, Staffilani, Takaoka and Tao and bilinear estimates by Bejenaru, Herr, Holmer and Tataru. A polynomial growth bound for the solution is also given.
