Resumen:
I derive the stochastic equation for the perturbations of the metric for a gauge-invariant energy-momentum tensor in stochastic inflation. A quantization for the field that describes the gauge-invariant perturbations for the metric is developed. In a power-law expansion for the universe the amplitude for these perturbations on a background metric could be very important in the infrared sector.
