Conformally Flat Pseudoprojective Symmetric Spacetimes in fR,G Gravity
Sufficient conditions on a pseudoprojective symmetric spacetime PPSn whose Ricci tensor is of Codazzi type to be either a perfect fluid or Einstein spacetime are given. Also, it is shown that a PPSn is Einstein if its Ricci tensor is cyclic parallel. Next, we illustrate that a conformally flat PP...
