Cosmological Model with Global Equation of State in Presence of G & Λ

Abstract

In this paper generalized cosmological model is obtained in the presence of global equation of state of the form p = (1/3)ρ𝜙 where 𝜙 is a scale factor. Also discussed the cases of matter dominated universe and radiation dominated universe under the condition of G = G₀(R/R₀)^n-2. The corresponding physical interpretations of the cosmological solution are also discussed.
