초록

The W5-curvature tensor has been studied in the space- time of general relativity. The space-time satisfying Einstein's field equations with cosmological term and vanishing W5-curvature tensor has been considered and it has been shown that metric tensor is proportional to the energy-momentum tensor. The existence of Killing as well as conformal Killing vector fields have been shown. Further for a W5-flat perfect fluid space-time satisfying Einstein's field equations, the isotropic pressure has been found to be the function of cosmological constant and non-zero gravitational constant.
