Abstract

Cosmological solutions in a higher derivative theory have been obtained with an imperfect fluid. We consider both power law and exponential models of the early universe. We discuss cosmological models in the Eckart, truncated and full causal theories. In the full-causal theory, we distinguish between two cases, one with the temperature obeying a power law behavior and the other relaxing this assumption. The exponential solution permits a realistic scenario when the behavior of the temperature is not of the power-law type.
