Evolution of cosmological perturbations in a stage dominated by an oscillatory scalar field
Hideo Kodama, Takashi Hamazaki
In the investigation of the evolution of cosmological perturbations in inflationary universe models the behavior of perturbations during the reheating stage is the most unclear poi…

Evolution of Cosmological Perturbations during Reheating
Takashi Hamazaki, Hideo Kodama
The behavior of scalar perturbations on superhorizon scales during the reheating stage is investigated by replacing the rapidly oscillating inflaton field by a perfect fluid obtain…
