Bulk viscosity and the inflationary universe

Phase transitions from a universe with nonnegligible bulk viscosity to an inflationary one are possible only if viscosity virtually disappears in the process. This suggests the phase change involved is of the type normal fluid to superfluid. Some exact solutions of Einstein equations for a viscous fluid are also given. They show the subtle interplay of viscosity and equations of state.
