Abstract:
This paper aims to study the W-curvature tensor on relativistic space-times. The energy-momentum tensor T of a space-time having a semi-symmetric W-curvature tensor is semi-symmetric, whereas the whereas the energy-momentum tensor T of a spacetime having a divergence free W-curvature tensor is of Codazzi type. A space-time having a traceless W-curvature tensor is Einstein. A W-curvature flat space-time is Einstein. Perfect fluid space-times which admits W-curvature tensor are considered.
