A black hole hologram in de Sitter space

TL;DR

This paper demonstrates that the entropy of de Sitter space containing a black hole can be explained using a modified Cardy-Verlinde formula, highlighting observer dependence of the entropy in such spacetimes.

Contribution

It introduces a modified Cardy-Verlinde entropy formula applicable to de Sitter space with black holes, advancing the holographic understanding of cosmological horizons.

Findings

Entropy of de Sitter space with black holes can be derived from a modified Cardy-Verlinde formula.

Observer dependence of de Sitter entropy is discussed.

Provides a holographic perspective on cosmological horizons.

Abstract

In this paper we show that the entropy of de Sitter space with a black hole in arbitrary dimension can be understood using a modified Cardy-Verlinde entropy formula. We also comment on the observer dependence of the de Sitter entropy.
