Predictions of inflation: the slow roll approximation vs. exact results
Dominik J. Schwarz, Jerome Martin
Inflation predicts the generation of cosmological perturbations. Usually, the power spectra for the scalar and tensor modes are calculated with help of the slow roll approximation.…

Amplitude of superhorizon cosmological perturbations
Jerome Martin, Dominik J. Schwarz
We study the influence of reheating on super-horizon density perturbations and gravitational waves. We correct wrong claims [L. P. Grishchuk Phys. Rev. D 50, 7154 (1994) and gr-qc/…

Reply to `Comment on ``The influence of cosmological transitions on the evolution of density perturbations'' '
Jerome Martin, Dominik J. Schwarz
We reply to L.P. Grishchuk's comment (gr-qc/9801011) on our paper ``The Influence of Cosmological Transitions on the Evolution of Density Perturbations'' (Phys. Rev. D 57, 3302, 19…
