The entropy for a black hole in a de Sitter space is approached within the frame-work of spacetime foam. A simple model made by N wormholes in a semiclassical approximation, is taken under examination to compute the entropy for such a case. An extension to the extreme case when the black hole and cosmological horizons are equal is discussed.

Abstract
The entropy for a black hole in a de Sitter space is approached within the frame-work of spacetime foam. A simple model made by N wormholes in a semiclassical approximation, is taken under examination to compute the entropy for such a case. An extension to the extreme case when the black hole and cosmological horizons are equal is discussed.File allegato/i alla scheda:
