Future infinity, solipsism and de Sitter holography
abstract
We explore several aspects of asymptotically de Sitter spacetimes. We begin with an overview of some of the properties of future infinity, the natural boundary of such a spacetime. Subsequently we delve into potential holographic descriptions of such spaces, with a dual Euclidean theory living at the boundary. As an example we discuss asymptotically de Sitter space in higher spin Vasiliev gravity and a recent proposal for a dual theory. We end by exploring some properties of the static patch, the region of the local de Sitter observer.
