无紧支撑的二维非线性Wave Equations的整体适定性

Global Well-posedness for 2D Nonlinear Wave Equations without Compact Support

Yuan Cai, Zhen Lei, Nader Masmoudi

摘要:

在[2]的重要工作中,Alinhac证明了二维拟线性波动方程在零条件下整体小解的存在性。证明严重依赖于初始数据具有紧支持的事实[22]。这一限制是否可以取消还不清楚。本文对零条件下的完全非线性波动方程,在没有紧支撑的情况下,证明了小初值下的整体适定性。此外,我们还将所得结果应用于一类拟线性波动方程。

英文摘要:

In the significant work of [2], Alinhac proved the global existence of small solutions for 2D quasilinear wave equations under the null conditions. The proof heavily relies on the fact that the initial data have compact support [22]. Whether this constraint can be removed or not is still unclear. In this paper, for fully nonlinear wave equations under the null conditions, we prove the global well-posedness for small initial data without compact support. Moreover, we apply our result to a class of quasilinear wave equations.
