Query: Perturbations in inflationary cosmologies with smooth exit   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.
