Bulk Viscous Cosmological Model in Brans-Dicke Theory with New Form of Time Varying Deceleration Parameter

الملخص EN

We have presented FRW cosmological model in the framework of Brans-Dicke theory.

This paper deals with a new proposed form of deceleration parameter and cosmological constant Λ.

The effect of bulk viscosity is also studied in the presence of modified Chaplygin gas equation of state (p=Aρ-B/ρn).

Furthermore, we have discussed the physical behaviours of the models.
