On Bianchi type III Cosmological Model with Quadratic EoS in Lyra Geometry
arXiv:1901.05962 · doi:10.1142/S0219887818501943
Abstract
The paper deals with the investigation of a homogeneous and anisotropic space-time described by Bianchi type III metric with perfect fluid in Lyra geometry setting. Exact solutions of the Einsten's field equations have been obtained under the assumption of quadratic equation of state (EoS) of the form p=a(rho)^2-(rho), where a is a constant and strictly a>0. The physical and geometrical aspects are also examined in details.
