Reissner-Nordstrom-de Sitter black hole, planar coordinates and dS/CFT

TL;DR

This paper explores Reissner-Nordstrom-de Sitter black holes within the dS/CFT framework, analyzing boundary stress tensors, mass, and RG flow changes across different coordinate systems, including multi-black hole solutions.

Contribution

It provides new insights into how black holes are represented in the dual boundary theory using planar coordinates and compares dS and AdS configurations.

Findings

Black holes appear as punctures in the dual boundary theory in planar coordinates.

The boundary stress tensor and mass are explicitly computed for these solutions.

RG flow behavior varies with different foliations of spacetime.

Abstract

We discuss the Reissner-Nordstrom-de Sitter black holes in the context of dS/CFT correspondence by using static and planar coordinates. The boundary stress tensor and the mass of the solutions are computed. Also, we investigate how the RG flow is changed for different foliations. The Kastor-Traschen multi-black hole solution is considered as well as AdS counterparts of these configurations. In particular, we find that in planar coordinates the black holes appear like punctures in the dual boundary theory.
