三维散焦、三次、非线性wave equation的整体适定性,径向初始为$\dot{H}^{s} \times \dot{H}^{s - 1}$、$s > \frac{1}{2}$

Global well - posedness for the defocusing, cubic, nonlinear wave equation in three dimensions for radial initial in $\dot{H}^{s} \times \dot{H}^{s - 1}$, $s > \frac{1}{2}$

摘要:

本文研究三维空间中具有径向初值的三次非线性离焦波动方程。临界空间为$\dot{H}^{1/2} \times \dot{H}^{-1/2}$。我们证明了如果初始数据是径向的并且对于某些$s > \frac{1}{2}$位于$(\dot{H}^{s} \times \dot{H}^{s - 1}) \cap (\dot{H}^{1/2} \times \dot{H}^{-1/2})$中,则三次初值问题是全局适定的.我们使用的是I -方法和长时间的Escherichartz估计.该方法与[D2]中使用的方法非常相似。

英文摘要:

In this paper we study the defocusing, cubic nonlinear wave equation in three dimensions with radial initial data. The critical space is $\dot{H}^{1/2} \times \dot{H}^{-1/2}$. We show that if the initial data is radial and lies in $(\dot{H}^{s} \times \dot{H}^{s - 1}) \cap (\dot{H}^{1/2} \times \dot{H}^{-1/2})$ for some $s > \frac{1}{2}$, then the cubic initial value problem is globally well - posed. We use the I - method and the long time Strichartz estimates. This method is quite similar to the method used in [D2].
