Bianchi Type-V model with a perfect fluid and Λ-term

Abstract

A self-consistent system of gravitational field with a binary mixture of perfect fluid and dark energy given by a cosmological constant has been considered in Bianchi Type-V universe. The perfect fluid is chosen to be obeying either the equation of state p = γρ with γ ε [0, 1] or a van der Waals equation of state. The role of Λ-term in the evolution of the Bianchi Type-V universe has been studied. © Indian Academy of Sciences.
