Descripción
We consider the contribution to the entropy from the fluctuations of a scalar field in the background of a curved time-independent metric. To account for the curvature of space, we postulate a position-dependent cutoff that depends on energy. With this cutoff, we calculate the scalar contribution in a background anti-de Sitter space, the exterior of a black hole, and de Sitter space.In all cases, we find results that can be simply interpreted in terms of local energy and proper volume, yielding insight into why a theory appears to be holographic.
