Energy density and pressure of the Stefani's universe with radiation and negative spatial curvature
Observational data of last decades show the accelerated expansion of our Universe. This fact can be explained if we consider Einstein's equations with uniform energy density and non-uniform pressure. In this paper we study one of these solutions for shiftless perfect fluid.
