Abstract

The full (nontruncated) Israel-Stewart theory of bulk viscosity is applied to dissipative FRW spacetimes. Dimensionless variables and dimensionless equations of state are used to write the Einstein-thermodynamic equations as a plane autonomous system and the qualitative behavior of this system is determined. Entropy production in these models is also discussed.
