Abstract

We consider Kaluza−Klein FRWmodel with modified cosmic Chaplygin gas in the presence of variable cosmological constant – by including shear and bulk viscosity. By using numerical analysis we have investigated behavior of energy density  and Hubble parameter H. To study effect of bulk and shear viscosity on the cosmological parameters, we have obtained analytical solution for some particular choices of m, n and . Finally we discussed stability of the model.
