Beschreibung
Zusammenfassung:	Int.J.Mod.Phys. D12 (2003) 1603-1614 Considering the physical 3-space t = constant of the spacetime metrics as spheroidal and pseudo spheroidal, cosmological models which are generalizations of Robertson-Walker models are obtained. Specific forms of these general models as solutions of Einstein's field equations are also discussed in the radiation- and the matter-dominated eras of the universe.
