论文摘要
在对空间表征和分类的Cartan-Karlhede程序的现有实现中，由两种类型的索引对称地对称的多索引两分量旋转器播放了一个突出的Rôle。本文考虑了此类旋转器的无效旋转不变性的条件和检测，并纠正了先前的讨论。
In the existing implementations of the Cartan-Karlhede procedure for characterization and classification of spacetimes, a prominent rôle is played by multi-index two-component spinors symmetrized over both types of index. This paper considers the conditions for, and detection of, null rotational invariance of such spinors, and corrects a previous discussion.
