BIANCHI TYPE V UNIVERSES WITH BULK VISCOSITY IN GENERAL RELATIVITY

摘要

Bianchi type V bulk viscous fluid cosmological models are investigated. Using a generation technique (Camci {it et al.}, 2001), it is shown that the Einstein's 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 mass density. Solutions for particular forms of cosmic scale functions are also obtained. Some physical and geometric aspects of the models are also discussed.
