电磁场和相关的CR嵌入

Null electromagnetic fields and relative CR embeddings

Jonathan Earl Holland, George Sparling

摘要:

本文应用相对CR嵌入的概念研究了两个相关问题。首先,它否定地回答了Penrose提出的问题,即是否每一个无切变的零旋转同余都是解析的。其次,证明了给定任意无剪切零旋转同余,存在一个零电磁场,且该零电磁场关于该零旋转同余为零。在回答这些问题的过程中,我们介绍了一些新的技术,研究零电磁场和剪切自由同余一般的概念的基础上的相对CR嵌入。

英文摘要:

This paper applies the notion of relative CR embeddings to study two related questions. First, it answers negatively the question posed by Penrose whether every shear-free null rotating congruence is analytic. Second, it proves that given any shear-free null rotating congruence, there exists a null electromagnetic field which is null with respect to the given congruence. In the course of answering these questions, we introduce some new techniques for studying null electromagnetic fields and shear-free congruences in general based on the notion of a relative CR embedding.
