Bulk Reconstruction in De Sitter space time.

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 operators. It has also been extended to heavy scalar fields (i.e fields in the principal series representation)in de Sitter space time. In this talk I will carry out bulk reconstruction 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.
