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

The covariant approach to LRS perfect fluid spacetime geometries
Classical and Quantum Gravity, 1996 The dynamics of perfect uid spacetime geometries which exhibit Local Rotational Symmetry (LRS) are reformulated in the language of a 1+ 3 "threading " decomposition of the spacetime mani-fold, where covariant uid and curvature variables are ...
