Mass, entropy, and holography in asymptotically de Sitter spaces
Mass, entropy, and holography in asymptotically de Sitter spaces
We propose a novel prescription for computing the boundary stress tensor and charges of asymptotically de Sitter (dS) spacetimes from data at early or late time infinity. If there is a holographic dual to dS spaces, defined analogously to the AdS/conformal field theory correspondence, our methods compute the (Euclidean) stress …
