The central charge matrix has four generic eigenvalues. The area is proportional to the square root of the invariant quartic form of $E_{7(7)}$. It vanishes in all cases when 1/4 or 1/2 of supersymmetry is unbroken. The supergravity non-renormalization theorem for the area of the horizon in N=8 case protects the unique U-duality invariant.","authors_text":"Barak Kol, Renata Kallosh","cross_cats":[],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"1996-02-05T06:41:39Z","title":"E(7) Symmetric Area of the Black Hole Horizon"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/9602014","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:dff6ad4c262d56884aa78be3a0122f39483cd9d88c7e77357d1a0d9e832d2e4a","target":"record","created_at":"2026-07-04T17:18:28Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"4472c74332518159e108fa8ae01da55dfb00dd03e11300ecd45f357dec1a4a76","cross_cats_sorted":[],"license":"","primary_cat":"hep-th","submitted_at":"1996-02-05T06:41:39Z","title_canon_sha256":"b327d2058efd34efd1c809bcd59afa988754e966c0bca64f969c549c2f99409d"},"schema_version":"1.0","source":{"id":"hep-th/9602014","kind":"arxiv","version":2}},"canonical_sha256":"78e3ef4c1ea343819497d8a502fdffb852e5cb1874fa76a7264bd74178090434","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"78e3ef4c1ea343819497d8a502fdffb852e5cb1874fa76a7264bd74178090434","first_computed_at":"2026-07-04T17:18:28.827637Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T17:18:28.827637Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qWr30KY9Avc/Y96SM/6/JTwJc8D/L8MV8x79370MNl7mGD8BdHyQBCahezYcYM8Gjlyt5ZSutMvQmISHNqqCDA==","signature_status":"signed_v1","signed_at":"2026-07-04T17:18:28.827989Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/9602014","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:dff6ad4c262d56884aa78be3a0122f39483cd9d88c7e77357d1a0d9e832d2e4a","sha256:286d1fa6b18dc14e10ec323bf7b0f4f066704a3648cf0fa83910738880c984ab"],"state_sha256":"6bdc87b2c26d96c8aae55d73dd8e9559e150e52673bf0ec30d45681f9bb93700"}
