Primordial fluctuations of the metric in the warm inflation scenario
arXiv:gr-qc/0005072
Abstract
I consider a semiclassical expansion of the scalar field in the warm inflation scenario. I study the evolution for the fluctuations of the metric around the Friedmann-Robertson-Walker one. The formalism predicts that, in the power-law expansion universe, the fluctuations of the metric decreases with time.
