Abstract

In holography, the bulk reconstruction program has its origin in the context of AdS/CFT correspondence. While the AdS/CFT correspondence maps bulk fields to boundary CFT operators. A corresondence has been proposed for Desitter space but there are some ambiguity for the light scalars.

In this talk I will carry out bulk reconstruction in dS, obtain boundary representations for scalars of all masses as well as higher spin fields. This extrapolated map also extended the construction from Bunch-Davies to α- vacuum.
