摘要：
In this paper one examines analytical solutions for flat and non-flat universes composed by four components namely hot matter (ultra-relativistic), warm matter (WM) (relativistic), cold matter (CM) (non-relativistic) and cosmological constant. The WM is treated as a reduced relativistic gas (RRG) and the other three components are treated in the usual way. The solutions achieved contains one, two or three components of which one component is of WM type. A solution involving all the four components was not found.
