Perfect Fluid Spacetimes and Gradient Solitons

Journal of Nonlinear Mathematical Physics, 2022
This article deals with the investigation of perfect fluid spacetimes endowed with concircular vector field. It is shown that in a perfect fluid spacetime with concircular vector field, the velocity vector field annihilates the conformal curvature tensor
