摘要 如果薛定谔部分的 L2 范数足够小,二维 Zakharov 系统对于没有有限能量的数据具有唯一的全局解。该证明使用了最初由 Colliander、Keel、Staffilani、Takaoka 和 Tai 发起的改进的 I 方法。还给出了解的多项式增长界。
Abstract The two-dimensional Zakharov system is shown to have a unique global solution for data without finite energy if the L2-norm of the Schrödinger part is small enough. The proof uses a refined I-method originally initiated by Colliander, Keel, Staffilani, Takaoka and Tao. A polynomial growth bound for the solution is also given.
