Query: Amplitude of superhorizon cosmological perturbations   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/9801011] about the joining of perturbations at
cosmological transitions and about the quantization of cosmological
perturbations.
