研究了(2+1)维Minkowski时空中Maxwell-Klein-Gordon方程的整体存在性问题。我们首先通过专门研究洛伦兹规范和应用标准技术,在合适的索博列夫空间中建立了局部存在性。然后通过证明解的适当范数在有限时间内不能爆破来证明全局存在性。证明的一个重要步骤是证明某种二阶“能量”不会爆炸。
We study the global existence problem for the Maxwell–Klein–Gordon equations in (2+1)‐dimensional, Minkowski spacetime. We first establish local existence, in a suitable Sobolev space, by specializing to the Lorentz gauge and applying standard techniques. We then prove global existence by showing that an appropriate norm of the solutions cannot blow up in a finite time. An essential step in the proof involves showing that a certain second order ’’energy’’ does not blow up.
