Doubly torqued vectors and a classification of doubly twisted and Kundt spacetimes / C.A. Mantica, L.G. Molinari. - In: GENERAL RELATIVITY AND GRAVITATION. - ISSN 0001-7701. - 53:4(2021), pp. 48.1-48.11. [10.1007/s10714-021-02819-x]
Abstract:
The simple structure of doubly torqued vectors allows for a natural characterization of doubly twisted down to warped spacetimes, as well as Kundt spacetimes down to PP waves. For the first ones the vectors are timelike, for the others they are null. We also discuss some properties, and their connection to hypersurface orthogonal conformal Killing vectors, and null Killing vectors.
