Vacuum fluctuation in a 4D spacetime due an evolving non-compact
extra-dimension    [PDF]

Wagner Utiel

With a exactly expression for the Bogulobov coefficients we study a Robertson-Walker universe embeded in a 5D bulk with an evolving non-compact extra-dimension. The contribution to the vacuum fluctuation in the 4D universe due a coupled scalar field in the bulk is analised.
