It is shown that consistent boundary conditions exist, for which the asymptotic symmetry generators form one copy of the Virasoro algebra with central charge c_L=12J / \\hbar. This implies that the near-horizon quantum states can be identified with those of (a chiral half of) a two-dimensional conformal field theory (CFT). Moreover, in the extreme limit, the Frolov-Thorne vacuum state reduces to a thermal density matrix with dimensionless temperature T_L=1/2\\pi and conjugate energy given by the zero mode generator, L_0, of the Virasoro algebra. Assuming unitarity, the Cardy formula then gives a microscopic entropy S_{micro}=2\\pi J / \\hbar for the CFT, which reproduces the macroscopic Bekenstein-Hawking entropy S_{macro}=Area / 4\\hbar G. The results apply to any consistent unitary quantum theory of gravity with a Kerr solution. We accordingly conjecture that extreme Kerr black holes are holographically dual to a chiral two-dimensional conformal field theory with central charge c_L=12J / \\hbar, and in particular that the near-extreme black hole GRS 1915+105 is approximately dual to a CFT with c_L \\sim 2 \\times 10^{79}.","external_url":"https://arxiv.org/abs/0809.4266","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-24T19:39:51.724584+00:00","pith_arxiv_id":"0809.4266","created_at":"2026-05-11T22:46:13.572706+00:00","updated_at":"2026-05-24T19:39:51.724584+00:00","title_quality_ok":false,"display_title":"The Kerr/CFT correspondence","render_title":"The Kerr/CFT correspondence"},"hub":{"state":{"work_id":"941fbc66-e29c-486e-9ce5-748d66443c9f","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":10,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2016-08-22T12:32:49+00:00","last_pith_cited_at":"2026-05-16T03:54:11+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":"2026-06-01T04:33:11.305778+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":1}],"polarity_counts":[{"context_polarity":"background","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
