The Cardy-Verlinde formula and entropy of Topological Reissner-Nordström black holes in de Sitter spaces

Abstract

In this paper we discuss the question of whether the entropy of cosmological horizon in Topological Reissner-Nordström- de Sitter spaces can be described by the Cardy-Verlinde formula, which is supposed to be an entropy formula of conformal field theory in any dimension. Furthermore, we find that the entropy of black hole horizon can also be rewritten in terms of the Cardy-Verlinde formula for these black holes in de Sitter spaces, if we use the definition due to Abbott and Deser for conserved charges in asymptotically de Sitter spaces. Our result is in favour of the dS/CFT correspondence.
