# Constraints on the general solutions of Einstein cosmological equations by Hubble parameter times cosmic age: a historical perspective

@article{Gonzalo2013ConstraintsOT, title={Constraints on the general solutions of Einstein cosmological equations by Hubble parameter times cosmic age: a historical perspective}, author={Julio A. Gonzalo and Manuel Alfonseca}, journal={arXiv: General Physics}, year={2013} }

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 {\Lambda}CDM ({\Lambda} Cold Dark Matter), KOFL (k Open Friedman-Lemaitre), plus two mixed solutions are investigated, under the constraints imposed by the relatively narrow current uncertainties…
