Hamiltonian charges in the asymptotically de Sitter spacetimes
Hamiltonian charges in the asymptotically de Sitter spacetimes
A bstract We generalize a notion of āconservedā charges given by Wald and Zoupas to the asymptotically de Sitter spacetimes. Surprisingly, our construction is less ambiguous than the one encountered in the asymptotically flat context. An expansion around exact solutions possessing Killing vectors provides their physical meaning. In particular, we ā¦
