Isotropic Robertson-Walker model universe with dynamical cosmological parameter Λ in Brans-Dicke Theory of Gravitation

Kangujam Priyokumar Singh, Mukunda Dewri

Abstract


This paper discusses about Robertson-Walker space-time with quadratic equation of state and dynamical cosmological parameter Λ . Some exact solutions of Einstein’s field equations for three cases have been obtained. Physical behaviors of the models are discussed in detail.


Keywords


Brans-Dicke Theory, Dark Energy, Quadratic equation of state.
