On the evolution of scalar metric perturbations in an inflationary cosmology
On the evolution of scalar metric perturbations in an inflationary cosmology
We further clarify how scalar metric perturbations are amplified in an inflationary cosmology. We first construct a simple, analytic model of an inflationary cosmology in which the expansion scale factor evolves continuously from an inflationary era to a radiation-dominated era. From this model, it is clear to see how scalar …
