Abstract
In a historical perspective, compact solutions of Einstein’s equations, including the
cosmological constant and the curvature terms, are obtained, starting from two recent
observational estimates of the Hubble’s parameter (H0) and the “age” of the universe (t0).
Cosmological implications for ΛCDM (Λ Cold Dark Matter), KOFL (k Open FriedmanLemaitre),
plus two mixed solutions are investigated, under the constraints imposed by
the relatively narrow current uncertainties. Quantitative results obtained for the KOFL
case seem to be compatible with matter density and the highest observed red-shifts from
distant galaxies, while those obtained for the ΛCDM may be more difficult to reconcile.
