Symmetries of fâassociated standard static spacetimes and applications
Abstract
The purpose of this note is to study and explore some collineation vector fields on standard static spacetimes Ifâ¯Ãâ¯M(also called fâ associated SSST). Conformal vector fields, Ricci and matter collineations are studied. Many implications for the existence of these collineations on fâassociated SSSTs are obtained. Moreover, Ricci soliton structures on fâ associated SSSTs admitting a potential conformal vector field are considered.
