Inflationary scenarios with scale-invariant spectral tensorial index
César A. Terrero-Escalante, Eloy Ayón-Beato, Alberto A. García
Next-to-leading order expressions related to Stewart-Lyth inverse problem are used to determine the inflationary models with a tensorial power spectrum described by a scale-invaria…
On the Stewart-Lyth Inverse Problem
Eloy Ayón-Beato, Alberto García, Ricardo Mansilla +1
In this paper the Stewart-Lyth inverse problem is rewritten using the comoving scales as the basic parameter. It is shown that some information on the inflaton potential can be obt…
Stewart-Lyth Inverse Problem
Eloy Ayón-Beato, Alberto García, Ricardo Mansilla +1
In this paper the Stewart-Lyth inverse problem is introduced. It consists of solving two non-linear differential equations for the first slow-roll parameter and finding the inflato…
