波映射的无条件适定性

Unconditional well-posedness for wave maps

Fabrice Planchon, Nader Masmoudi

摘要:

我们证明了波映射方程在自然类,即$ (u, \partial_t u) \in C([0,T); \dot{H}^{d/2})\times C^1([0,T); \dot{H}^{d/2-1})$在维度$d\geq 4$的解的唯一性。这是通过在较低的正则性水平下估计两个解的差来实现的。为了简化到库仑规范,必须将规范变化局部化在合适的锥中,并估计与每个解相关联的框架和连接之间的差异,并利用目标流形具有有界曲率的假设。

英文摘要:

We prove uniqueness of solutions to the wave map equation in the natural class, namely $ (u, \partial_t u) \in C([0,T); \dot{H}^{d/2})\times C^1([0,T); \dot{H}^{d/2-1})$ in dimensions $d\geq 4$. This is achieved through estimating the difference of two solutions at a lower regularity level. In order to reduce to the Coulomb gauge, one has to localize the gauge change in suitable cones as well as estimate the difference between the frames and connections associated to each solutions and take advantage of the assumption that the target manifold has bounded curvature.
