We construct nonlinear inflaton potential-energy densities and compute tilted primordial spatial inhomogeneity power spectra in closed and open inflation models. These new tilted power spectra differ from the ones previously used in nonflat cosmological models.
We construct nonlinear inflaton potential-energy densities that describe not necessarily very slowly rolling closed and open inflation models, and compute tilted primordial spatial inhomogeneity power spectra that follow from quantum-mechanical fluctuations during inflation in these models. Earlier nonflat inflation model power spectra computations assumed an inflaton potential-energy density with a linear slope that resulted in very slow roll during inflation and untilted power spectra. These new tilted power spectra differ from those that have previously been used to study cosmological data in nonflat cosmological models.
