Two-Fluid Cosmological Models In a Bianchi Type I Space-Times With Variable G and Λ

S. P. Kandalkar and S. W. Samdurkar

This paper presents anisotropic, homogeneous two-fluid cosmological models in a Bianchi type I space-time with a gravitational constant G and cosmological constant Λ . In the two-fluid model, one fluid represents the matter content of the universe and another fluid is chosen to model the CMB radiation. The radiation and matter content of the universe are in an interactive phase. We also discuss the behaviour of associated fluid parameters and kinematical parameters.
