Bianchi Type-I bulk viscous fluid string dust magnetized cosmological model in general relativity

摘要

Bianchi Type-I magnetized bulk viscous fluid string dust cosmological model is investigated. To get a determinate model, we have assumed the conditions σ ∝ θ and ζθ — constant where a is the shear, θ the expansion in the model and ζ the coefficient of bulk viscosity. The behaviour of the model in the presence and absence of magnetic field together with physical and geometrical aspects of the model are also discussed.
