Reconstructing inflation in a generalized Rastall theory of gravity
Ramon Herrera, Carlos Rios
We investigate the reconstruction of standard and generalized Rastall gravity inflationary models, using the scalar spectral index and the Rastall parameter expressed as functions…

Reconstructing inflation and reheating in the framework of a generalized Friedmann equation
Ramon Herrera, Carlos Rios
The reconstruction of an inflationary universe considering the parametrization of the scalar spectral index as a function of the number of folds in the framework of a modified…

Speed of sound and scalar spectral index: Reconstructing inflation and reheating in a non-canonical theory
Ramon Herrera, Carlos Rios
In this article we analyze the reconstruction of inflation in the framework of a non-canonical theory. In this sense, we study the viability of reconstructing the background variab…
