Ricci Soliton and Geometrical Structure in a Perfect Fluid Spacetime with Torse-forming Vector Field
arXiv:1806.00599
Abstract
In this paper geometrical aspects of perfect fluid spacetime with torse-forming vector field ξare discribed and Ricci soliton in perfect fluid spacetime with torse-forming vector field ξare determined. Conditions for the Ricci soliton to be expanding, steady or shrinking are also given.
