Perturbations in inflationary cosmologies with smooth exit
Daniel Tilley, Roy Maartens
Abstract
We give a comprehensive analysis of how scalar and tensor perturbations evolve in cosmologies with a smooth transition from power-law-like and de Sitter-like inflation to a radiation era. Analytic forms for the super-horizon and sub-horizon perturbations in the inflationary and radiation dominated eras are found.
