For the case of dS_3, which is analyzed in some detail, the central charge of the CFT_2 is computed in an analysis of the asymptotic symmetry group at I^\\pm. This dS/CFT proposal is supported by the computation of correlation functions of a massive scalar field. In general the dual CFT may be non-unitary and (if for example there are sufficently massive stable scalars) contain complex conformal weights. We also consider the physical region O^- of dS_3 corresponding to the causal past of a timelike observer, whose holographic dual lives on a plane rather than a sphere. O^- can be foliated by asymptotically flat spacelike slices. Time evolution along these slices is generated by L_0+\\bar L_0, and is dual to scale transformations in the boundary CFT_2.","external_url":"https://arxiv.org/abs/hep-th/0106113","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-22T15:54:58.501019+00:00","pith_arxiv_id":"hep-th/0106113","created_at":"2026-05-11T14:06:04.820367+00:00","updated_at":"2026-05-22T15:54:58.501019+00:00","title_quality_ok":false,"display_title":"The dS/CFT Correspondence","render_title":"The dS/CFT Correspondence"},"hub":{"state":{"work_id":"358db353-13ca-4022-a044-72903f02a0fb","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":20,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2025-05-05T23:22:00+00:00","last_pith_cited_at":"2026-05-15T21:31:11+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-06-04T15:57:46.825548+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":12}],"polarity_counts":[{"context_polarity":"background","n":11},{"context_polarity":"support","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
