Abstract / Bemerkung
Vacuum fluctuations in the inflaton field driving chaotic inflation with aquadratic potential give a red spectrum of primordial density perturbations,n=0.97. However angular fluctuations in an O(N)-symmetric quadratic potentialhave a very nearly scale-invariant spectrum, n=0.9998. We investigate thepossibility that these isocurvature field perturbations could give the dominantcontribution to the primordial density perturbation after inflation.
