On the general structure of Ricci collineations for type B warped space–times
On the general structure of Ricci collineations for type B warped space–times
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.
