Abstract
The Gibbs-Duhem equation dU + pdV = TdS imposes restrictions on the pe rfect fluid solutions of Einstein equations that have a one-dimensiona l symmetry group or no symmetry at all. In this paper, we investigate the restrictions imposed on the Stephani Universe and on the two class es of models found by Szafron. Upon the Stephani Universe and the beta 'not equal 0 class of Szafron symmetries are forced. We find the most general subcases of the beta'=0 model of Szafron that are consistent w ith the Gibbs-Duhem equation and have no symmetry. (C) 1997 American I nstitute of Physics.
