Effect of Varying Bulk Viscosity on Generalized Chaplygin Gas    [PDF]

H. Saadat, B. Pourhassan

In this paper, viscous generalized Chaplygin gas as a model of dark energy considered. We assume non-constant bulk viscous coefficient and study dark energy density. We consider several cases of density-dependent viscosities. We find that, in the special case, the viscous generalized Chaplygin gas is corresponding to modified Chaplygin gas.
