Accelerating Cosmological Models With Variable G and Λ-Term in General Relativity

Abstract: In this paper, we have presented a new class of accelerating universe models with variable cosmological term Λ(t) and gravitational constant G(t) in the framework of general relativity. To get exact solution of Einstein’s field equations for homogeneous and anisotropic Bianchi type-V space-time, a time varying de- celeration parameters is considered as q = 1 + nα , where n, α are constants. The present model shows a point type singularity at origin. The results establish the quintessence like behavior of model… Show more
