四维时空中非线性耦合波-Klein-Gordon方程组小振幅解的整体存在性

Global existence of small amplitude solutions to nonlinear coupled wave-Klein-Gordon systems in four space-time dimension with hyperboloidal foliation method

Yue MA

摘要:

在这篇文章中,我们将发展一种新的能量方法,它是基于时空的叶状成双曲超曲面。我们将看到,利用这种方法,拟线性波动方程和Klein-Gordon方程的正则解的整体存在性和几乎整体存在性等经典结果将以更简单、更自然的方式得到.最重要的是,我们建立了一般类型的耦合拟线性波动方程组的整体正则解的存在性。所有这些都表明,与经典方法相比,这种时空的双曲叶理可能是一种更自然的方式来看待波算子。

英文摘要:

In this article one will develop a new type of energy method based on a foliation of spacetime into hyperboloidal hypersurfaces . As we will see, with this method, some classical results such as global existence and almost global existence of regular solutions to the quasi-linear wave equations and Klein-Gordon equations will be established in a much simpler and much more natural way. Most importantly, the global existence of regular solutions to a general type of coupled quasilinear wave-Klein-Gordon system will be established. All of this suggests that compared with the classical method, this hyperboloidal foliation of space-time may be a more natural way to regard the wave operator.
