任意时空中的无力电动力学和叶状结构

Force-free Electrodynamics and Foliations in an arbitrary Spacetime

Govind Menon

摘要:

在本文中,我们制定无力电动力学和叶理之间的关系。背景度量被认为是预定的和电中性的,但在其他方面是任意的。事实证明,无力电动力学的解与具有规定性质的时空叶理的存在密切相关。我们还证明了一个局部存在唯一性定理,并提供了一个配方,当满足一定的条件时,构造唯一的解决方案/类的解决方案。我们用例子阐明了这个定理。我们还能够证明非零解接近零极限时的奇异性定理。在这里,我们也构造了一个明确的例子来说明奇异性定理。

英文摘要:

In this paper we formulate the relationship between force-free electrodynamics and foliations. The background metric, is considered predetermined and electrically neutral, but otherwise arbitrary. As it turns out, solutions to force-free electrodynamics is intimately connected to the existence of foliations of a spacetime with prescribed properties. We also prove a local existence and uniqueness theorem and provide a recipe for constructing the unique solution/class of solutions when certain conditions are met. We clarify the theorem with examples. We are also able to also prove a singularity theorem for when non-null solutions approach the null limit. Here too, we construct an explicit example to illustrate the singularity theorem.
