Viscous Cosmology and Thermodynamics of Apparent Horizon

Abstract

It is shown that the differential form of Friedmann equations of FRW universe can be recast as a similar form of the first law, $T_{h}d{S}_h=dE+WdV$, of thermodynamics at the apparent horizon of FRW universe filled with the viscous fluid. It is also shown that the generalized second law of thermodynamics holds at the apparent horizon of FRW universe and preserves dominant energy condition.
