In this paper we consider conformally flat $(QE)_4$ spacetime and obtained several important results. We study application of conformally flat $(QE)_4$ spacetime in general relativity and Ricci soliton structure in a conformally flat $(QE)_4$ perfect fluid spacetime.
Classification : 53C15 53C25
Keywords: Quasi-Einstein spacetime, perfect fluid spacetime, Einstein field equation, energy momentum tensor, Ricci solitons, conformal curvature tensor
