Sketching the inflaton potential
C. A. Terrero-Escalante
Based on solutions of the Stewart-Lyth inverse problem it is argued that in the CMB data analysis the parametrization of the primordial spectra from inflation must include the `run…

Is power-law inflation really attractive?
C. A. Terrero-Escalante
It is argued that the order of the analytic expressions for the calculation of the primordial perturbations from inflation exerts a strong influence upon the results of the analysi…

Is the observable Universe generic?
C. A. Terrero-Escalante, A. A. Garcia
Recently an inflationary potential yielding power spectra characterized by a scale-invariant tensorial spectral index and a scale-dependent scalar spectral index was introduced. We…
