Pierre Salati Université de Savoie & LAPTH • Constante cosmologique et observations : le test des supernovae SNeIa lointaines. • Quintessence et champ scalaire primordial. • Matière noire astronomique et champ scalaire.
The geometry is described by the Robertson-Walker metric Scale factor Observational evidence for a non-vanishing cosmological constant.
