Summary
A law of variation for Hubble’s parameter in evolutionary models, that yields a constant value for the deceleration parameter, is presented. It leads naturally to the exclusion of open universes.
Riassunto
Si presenta una legge di variazione per il parametro di Hubble nei modelli evolutivi, che dà un valore costante per il parametro di decelerazione. Essa porta naturalmente all'esclusione di universi aperti.
