The 2+1 black hole -characterized by mass, angular momentum and charge, defined by flux integrals at infinity- is quite similar to its 3+1 counterpart. Anti-de Sitter space appears as a negative energy state separated by a mass gap from the continuous black hole spectrum. Evaluation of the partition function yields that the entropy is equal to twice the perimeter length of the horizon.","external_url":"https://arxiv.org/abs/hep-th/9204099","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-25T07:25:28.924742+00:00","pith_arxiv_id":"hep-th/9204099","created_at":"2026-05-09T06:10:43.333306+00:00","updated_at":"2026-06-05T21:23:00.469572+00:00","title_quality_ok":true,"display_title":"The Black Hole in Three Dimensional Space Time","render_title":"The Black Hole in Three Dimensional Space Time"},"hub":{"state":{"work_id":"0cb80604-a5a4-4629-ad7b-756f3cb5ee4a","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":36,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"1997-11-27T23:53:13+00:00","last_pith_cited_at":"2026-05-21T22:20:23+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":"2026-06-11T07:17:42.409965+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":20}],"polarity_counts":[{"context_polarity":"background","n":19},{"context_polarity":"support","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
