Holography for QFTs in de Sitter

Abstract: I will discuss how to set up holography for QFTs in de Sitter by studying AdS gravity coupled to a scalar field in the bulk. The talk will start with a discussion of the subtleties and pitfalls in properly identifying the conformal boundary in asymptotically locally AdS spacetimes. We will then focus in the case the boundary geometry is de Sitter and compute the 1- and 2-point function of the dual QFT for a specific 4-dimensional bulk model.
