C-Field Cosmological models with bulk viscosity and variable G in flat FRW space-time
Department of Mathematics, University of Rajasthan Jaipur-302055 (INDIA)
Cosmological models with variable gravitational constant (G) and bulk viscosity in C-field cosmology for flat FRW space-time are investigated. To get the deterministic model of the universe, we have assumed G = Rn where R is the scale factor and n is a constant. Under this assumption, we have investigated two C-field cosmological models for two cases: (i) = constant, (ii) = constant, R 3R where is the coefficient of bulk viscosity, the expansion in the model. The physical and geometrical aspects of the models and the effect of bulk
viscosity related with the observation are discussed.
