Extended thermodynamics of Friedmann-Robertson-Walker models in the Landau-Lifshitz frame

The authors study dissipative Friedmann-Robertson-Walker (FRW) models with the help of the relativistic extended thermodynamics as formulated in the Landau-Lifshitz (energy) frame. The physically most relevant solutions are shown to tend asymptotically to models in which the initial material anisotropy due to the particle drift (diffusion) is washed out. Some recent results obtained by Turok (1988) and Barrow (1988) in a different context can be recovered.
