Plane-symmetric inhomogeneous magnetized viscous fluid universe with a variable $\Lambda$

Abstract

The behavior of magnetic field in plane symmetric inhomogeneous cosmological models for bulk viscous distribution is investigated. The coefficient of bulk viscosity is assumed to be a power function of mass density $(\xi ={\xi }_0{\rho }^n)$. The values of cosmological constant for these models are found to be small and positive which are supported by the results from recent supernovae Ia observations. Some physical and geometric aspects of the models are also discussed.
