To derive a power spectrum for energy density inhomogeneities in a closed universe, we study a spatially-closed inflation model. The constants of integration in the inflation epoch solutions are determined from Hawking’s prescription that the quantum state of the universe only include field configurations that are regular on the Euclidean section. The power spectrum we find is not a power law, and depends on spatial wavenumber in the way expected for a generalization to the closed model of the standard flat-space scale-invariant power spectrum.
