Tilted spatially nonflat inflation

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