Modified Chaplygin gas with bulk viscous cosmology in FRW (2+1)-dimensional spacetime
In this paper we study the bulk viscous cosmology by considering modified Chaplygin gas in the framework of ( 2 + 1 ) -dimensional spacetime. For this we consider various form of bulk viscosity coefficient ζ and then obtain the physical parameters energy density ρ , Hubble and deceleration parameter...

Zusammenfassung: | In this paper we study the bulk viscous cosmology by considering modified Chaplygin gas in the framework of
(

)
-dimensional spacetime. For this we consider various form of bulk viscosity coefficient
ζ
and then obtain the physical parameters energy density
ρ
, Hubble and deceleration parameters,
H
and
q
, respectively. Finally we discuss the stability of the model by using the speed of sound. |
