Totally symmetrized spinors and null rotation invariance
arXiv:2006.02177 · doi:10.1088/1361-6382/aba844
Abstract
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.
