We re-examine the brick-wall model in the context of spacetime foam. In particular we consider a foam composed by wormholes of different sizes filling the black hole horizon. The contribution of such wormholes is computed via a scale-invariant distribution. We obtain that the brick wall divergence appears to be logarithmic when the cutoff is sent to zero.

Abstract
We re-examine the brick-wall model in the context of spacetime foam. In particular we consider a foam composed by wormholes of different sizes filling the black hole horizon. The contribution of such wormholes is computed via a scale-invariant distribution. We obtain that the brick wall divergence appears to be logarithmic when the cutoff is sent to zero.File allegato/i alla scheda:
