We show how to construct a set of Euclidean conformal correlation functions on the boundary of a de Sitter space from an interacting bulk quantum field theory with a certain asymptotic behavior. We discuss the status of the boundary theory with respect to the reflection positivity and conclude that no obvious physical holographic interpretation is available.

Abstract
We show how to construct a set of Euclidean conformal correlation functions on the boundary of a de Sitter space from an interacting bulk quantum field theory with a certain asymptotic behavior. We discuss the status of the boundary theory with respect to the reflection positivity and conclude that no obvious physical holographic interpretation is available.
