Zusammenfassung: | 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. |
