从R^{3+1}到H^2的波映射的整体正则性

Global Regularity of Wave Maps from R^{3+1} to H^2

Joachim Krieger

摘要:

我们考虑了从R^{3+1}到双曲平面的具有光滑紧支撑的小H^{3/2}-范数初始数据的波映射,并证明了它们在时间上保持全局光滑。我们的方法是基于引入一个全球性的库仑规范,在最近的论文Shatah和Struwe,其次是动态分离,在早期的工作克莱纳曼和Machedon。然后,我们依赖于T.Tao在他最近的突破性成果Wave Maps中使用的方法,以适应低空间维度的球体。

英文摘要:

We consider Wave Maps with smooth compactly supported initial data of small H^{3/2}-norm from R^{3+1} to the hyperbolic plane and show that they stay smooth globally in time. Our methods are based on the introduction of a global Coulomb Gauge as in a recent paper by Shatah and Struwe, followed by dynamic separation as in earlier work of Klainerman and Machedon. We then rely on an adaptation of T.Tao's methods used in his recent breakthrough result on Wave Maps to spheres in low spatial dimensions.
