Principal and complementary series representations at the late-time boundary of de Sitter
arXiv:2205.11550 · doi:10.1007/978-981-19-4751-3_21
Abstract
We demonstrate how free massive scalar fields in the set up that usually appears in early universe inflationary studies, correspond to the principal series and complementary series representations of the group SO(d+1,1) by introducing late-time operators and computing their two-point functions.
