How probable is inflation?
Abstract
The HenneauxGibbonsHawkingStewart canonical measure on the set of classical universes is applied to a FriedmannRobertsonWalker model containing a massive scalar field. Although a uniform probability distribution in this measure would solve the flatness problem, it gives an ambiguous probability for inflation, since both the set of inflationary solutions and the set of noninflationary solutions have infinite measure.
