On the general structure of Ricci collineations for type B warped spacetimes
arXiv:gr-qc/0405133 · doi:10.1063/1.1775875
Abstract
A complete study of the structure of Ricci collineations for type B warped spacetimes is carried out. This study can be used as a method to obtain these symetries in such spacetimes. Special cases as 2+2 reducible spacetimes, and plane and spherical symmetric spacetimes are considered specifically.
