Primordial fluctuations of the metric in the warm inflation scenario
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 flat Friedmann-Robertson-Walker one. The formalism predicts that, in a power law expansion of the Universe, the fluctuations of the metric decr...

| Sumario: | 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 flat Friedmann-Robertson-Walker one. The formalism predicts that, in a power law expansion of the Universe, the fluctuations of the metric decrease with time. |
