Resumen:
We develop a stochastic approach to study gravitational waves produced during the inflationary epoch under the presence of a decaying cosmological parameter, on a 5D geometrical background which is Riemann flat. We obtain that the squared tensor metric fluctuations depend strongly on the cosmological parameter Ë(t) and we finally illustrate the formalism with an example of a decaying Ë(t). t) and we finally ilustrate the formalism with an example of a decaying Ë(t).
