What is Quantum Fields in de Sitter Space about?

This document summarizes a theory of two-point functions and generalized free quantum fields in de Sitter space. The authors present a theory that closely parallels the corresponding theory in Minkowski space. In de Sitter space, the usual spectral condition is replaced by a geodesic spectral condition, equivalent to a precise thermal characterization of vacuum states. The theory is based on the geometry of complex de Sitter space and introduces functions called perikernels that reproduce the structural pro
