Hypersurface-homogeneous bulk viscous fluid space-times with time-dependent cosmological term

Abstract

Some hypersurface-homogeneous cosmological models with bulk viscous fluid and time-dependent cosmological term are investigated. These expanding, shearing and non-rotating cosmological models of the universe evolve from initial big-bang singularities and give an essentially empty space for large times. Some physical and geometric behaviors of these models are also discussed. © Springer Science+Business Media B.V 2009.
