“…c 0 R n , where c 0 , n are constants. The resultant equations (2.23)-(2.26) clearly exhibit the essential influence of the viscous term on the values of σ, Λ and G. For ξ 0 = 0, the values of cosmological constants approach to the results discussed earlier in Khadekar and Ghogre [8]. From this study of the Bianchi I model, it is observed that such models are compatible with the results of recent observations.…”

The Bianchi type I cosmological model in the framework of Variable Speed of Light (VSL) theory is investigated, by taking into account the effect due to viscosity, considering p = p −3ζH where ζ = ζ 0 ρH −1 . The Einstein field equations are solved for variable G, c and Λ in which G, c, Λ and shear parameter σ 2 , all are coupled. It is shown that the viscosity term exhibits the influence on the form of solutions, in the framework of varying speed of light theory.

“…For approaching to more realistic model, the consideration of effect of viscosity mechanism is important. In the present paper, we have extended our previous work, Khadekar and Ghogre [8], by introducing a viscosity term as p = p − 3ξH.…”
