Bulk and Shear Viscosity in Early Universe |
I discuss recent results on influences of viscosity on QCD cosmology. In presence of viscous fluid coming from non-equilibrium thermodynamics for instance, essential cosmological variables should be redefined. The evolution of universe itself strongly depends on dissipative thermodynamics originating from such viscous era. Therefore, viscosity should be taken into account when we study dynamics and evolution of universe during the QCD era. |
