On Kantowski-Sachs Viscous Fluid Model in Bimetric Relativity
Kantowski-Sachs plane symmetric models are investigated in bimetric theory of gravitation proposed by Rosen [1] in the context of bulk viscous fluid. Taking conservation law and the equation of state, two different models of the universe are obtained. It is observed that Kantowski-Sachs vacuum model obtained in first case and bulk viscous fluid model obtained in second case. It is also observed that the bulk viscous cosmological model always represents an accelerated universe and consistent with the recent observations of type-1a supernovae. Some physical and geometrical features of the viscous fluid model are studied.
