FRW Cosmological Solutions with Zero-Mass Scalar Field Attached to Bulk Viscous Fluid in Saez-Ballester Theory of Gravitation

Abstract

In this paper, we have investigated spatially homogeneous isotropic Friedman cosmological models with zero–mass scalar field attached to bulk viscous fluid in Saez–Ballester theory of Gravitation. The cosmological models are obtained with the help of the special law of variation for Hubble’s parameter proposed by Bermann[1] and power law relation. Some physical properties of the models are discussed.
