By quantizing a suitably- generalized measure of the intrinsic curvature perturbation, the spectral indices as calculated in the Jordan frame now match those as calculated following a conformal transformation, in the Einstein frame.12pp. Plain LaTeX; no figuresAstrophysicsGeneral Relativity and Quantum Cosmologytext
