Cosmology B) Matter dominated: ρ > 0 , p = 0 Λ = 0: preferable class of models satisfies Einstein’s boundary criterion: empty space = flat space Base equations: ρ S 3 = ρ0 S 3 0 = constant ˙S 2 c2 = κ 3 ρ S 2 − k = C S − k ; C κ 3 ρ S 3 = constant which can be integrated elementary: dS/ √ C/S − k = ±c dt c○ 2009, F.
