Sezgin Altay Demirbag; Uday Chand De; Fusun Ozen Zengin;Abstract
The section 1 of this paper deals with the definition for a pseudo symmetric spacetime. In section 2, it is proved that a $(PZS)_4$ spacetime satisfying Codazzi type of $Z$-tensor does not exist. In which condition a $(PZS)_4$ spacetime can be a perfect fluid has been found as a necessary and sufficient condition.
After that, special properties are obtained if the $(PZS)_4$ spacetime has harmonic conformal curvature tensor.
