Perturbations in inflationary cosmologies with smooth exit

Daniel Tilley, R Maartens

Research output: Contribution to journalArticlepeer-review


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 superhorizon and subhorizon perturbations in the inflationary and radiation dominated eras are found.
