Three-Dimensional de Sitter Holography and Bulk Correlators at Late Time

ホログラフィーによる宇宙の始まりの探索 --新手法による初期宇宙の揺らぎの相関の計算--. 京都大学プレスリリース. 2022-08-10.We propose an explicitly calculable example of holography on three-dimensional de Sitter space by providing a prescription to analytic continue a higher-spin holography on three-dimensional anti–de Sitter space. Applying the de Sitter holography, we explicitly compute bulk correlation functions on three-dimensional de Sitter space at late time in a higher-spin gravity. These expressions are consistent with recent analysis based on bulk Feynman diagrams. Our explicit computations reveal how holographic computations could provide fruitful information
