Uniqueness of de Sitter and Schwarzschild-de Sitter spacetimes
Uniqueness of de Sitter and Schwarzschild-de Sitter spacetimes
We give a simple proof of the uniqueness of de Sitter and Schwarzschild-de Sitter spacetime without assuming extra conditions on the conformal boundary at infinity.Such spacetimes are the only solutions in the static class satisfying Einstein equations 4 R αβ = Λ 4 g αβ , where the cosmological constant …
