Exact Solution of Bianchi Type-V Model with Variable Cosmological Term- and G

Abstract

The homogeneous anisotropic Bianchi type􀀀V cosmological model with variable gravitational and cosmological constants is investigated. Exact solutions of the Einstein eld equations are presented in terms of adjustable parameter of quantum eld in a curved and expanding background. We found that the Cosmological constant decreases as time increases whereas the gravitational constants increases respectively. The universe in this model approaches isotropy state at late period of time. A clear presention for the physical and kinematical quantities of the model are also presented. vi
