• BIANCHI TYPE-I COSMOLOGICAL MODEL WITH CONSTANT DECELERATION PARAMETER IN SAEZ-BALLESTER THEORY OF GRAVITATION

Abstract

Bianchi type-I cosmological model in presence perfect fluid source in Saez-Ballester theory is investigated. Einstein’s field equations are solvable with help of variation law of Hubble parameter, which gives a constant value of deceleration parameter. The law generates power-law and exponential form of average scale factor in terms of cosmic time. Kinematical properties of the models are discussed. It has been shown that the solutions are compatible with recent observations.
