Ricci pseudo symmetric Anisotropic Fluid Spacetime admitting Hyperbolic solitons with Ricci vector field
As on arXiv
Abstract
This work focuses on an anisotropic fluid spacetime with these unique forms of the stress-energy tensor associated with radial pressure and a transverse pressure p. In an anisotropic fluid spacetime , we mani- fest curvatures symmetry such as Ricci pseudo-symmetric and prove that Ricci pseudo-symmetric anisotropic fluid spacetime is generalized quasi- Einstein spacetime. We deduce the Einstein gravitational field equation of Ricci pseudo-symmetric anisotropic fluid spacetime. In the framework of pseudo-Riemannian geometry, specifically, we study the quasi-conformal Ricci pseudo-symmetric anisotropic fluid spacetime, which exhibit the dark matter era. Moreover, we discuss the hyperbolic Ricci soliton and Hyperbolic Yamabe soliton on Ricci pseudo-symmetric anisotropic fluid spacetime with a time-like Ricci vector field. Finally, we turn up the char- acteristics of hyperbolic Ricci soliton and hyperbolic Yamabe soliton on Ricci pseudo-symmetric anisotropic fluid spacetime with a time-like Ricci vector field.
