Inflationary prediction for primordial non-gaussianity = La prediccion inflacionaria acerca de la no-gaussianidad primordial
We extend the Infinite N formalism so that it gives all of the stochastic properties of the primordial curvature perturbation if the initial ?eld perturbations are Gaussian. The calculation requires only the knowledge of some family of unperturbed universes. A formula is given for the normalization...
