Abstract

We consider the inverse function of the scale factor \(a(t)\) of the Friedmann equations, discussing also the asymptotics of cosmological parameters under various assumptions on the \(\Lambda\)CDM model. Using algebraic dependencies between the cosmological parameters and the representation of the inverse function of the scale factor \(a(t)\) as an elliptic integral with a parameter, we compute in a uniform way some special events in the universe’s evolution.
