چکیده
|
The main purpose of the present paper is about characterizing the properties of the perfect fluid space-time that admits the gradient ricci-bourguignon soliton. this gives some results about the stability of the energy-momentum tensor and also under some conditions pursues that a perfect fluid space-time is ricci symmetric. as a special case, when a perfect fluid space-time is equipped with the ricci-bourguignon soliton which has ricci biconformal vector field, we show that the metric of this space is einstein.
