Five dimensional FRW bulk viscous cosmological models in Brans-Dicke theory of gravitation

摘要

Five dimensional FRW space-time is considered in the presence of bulk viscous fluid in the frame work of Brans and Dicke (Phys. Rev. 124: 925, 1961) scalar-tensor theory of gravitation. To obtain determinate solution of the field equations we have used a power law between scalar field and the scale factor of the universe. Radiating flat, closed and open models are also presented. Physical properties of the models are also discussed.
