Abstract

Hypersurface–homogeneous cosmological models containing a bulk viscous fluid with time varying G and Λ have been presented We have shown that the field equations are solvable for any arbitrary cosmic scale function The viscosity coefficient of bulk viscous fluid is assumed to be a power function of the energy density Exact solutions of Einstein’s field equations are obtained which represent an expanding shearing and accelerating/decelerating models of the universe The physical and kinematical behaviours of the models are also discussed
