It is shown that the matter ring can affect the properties of the central object drastically. In particular, by virtue of the ring's frame dragging, the so-called Komar mass of the black hole or disc can become negative. A continuous transition from such discs to such black holes can be found.","authors_text":"David Petroff, Marcus Ansorg","cross_cats":[],"headline":"","license":"","primary_cat":"gr-qc","submitted_at":"2007-08-29T07:51:39Z","title":"Negative Komar Masses in Regular Stationary Spacetimes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0708.3899","kind":"arxiv","version":1},"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:de46c0201c7a3b713f73075d7fffc0a3aaad26de948c65307c4821ec512f99b4","target":"record","created_at":"2026-05-18T00:59:32Z","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":"8520b033a1ecfc582500a9fed01939bd17f2828ff9e1214bdce9f3f6d997803f","cross_cats_sorted":[],"license":"","primary_cat":"gr-qc","submitted_at":"2007-08-29T07:51:39Z","title_canon_sha256":"7eccf39e64fd7d9bb5cd3fc787b0c0514d2af9418db56c6881eedd3d427b63e1"},"schema_version":"1.0","source":{"id":"0708.3899","kind":"arxiv","version":1}},"canonical_sha256":"3a3b85db3eb0c7596bdfde0480a1297077b2678331c69aa74f5a734750af6239","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3a3b85db3eb0c7596bdfde0480a1297077b2678331c69aa74f5a734750af6239","first_computed_at":"2026-05-18T00:59:32.983546Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:59:32.983546Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8oqCG66lyp4UFkjGRHdP2jlqTaIxuxlXGmDfiBdSotA9OW8ANrJZsllCbY+egxkGjrdYORWinFGF4yJDi2xICw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:59:32.984075Z","signed_message":"canonical_sha256_bytes"},"source_id":"0708.3899","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:de46c0201c7a3b713f73075d7fffc0a3aaad26de948c65307c4821ec512f99b4","sha256:e5948019e97506f1768709f3de6de551a9e79fa2d6ccc6e2b894cfced82dc8c1"],"state_sha256":"fb15675d2a6531a2d8097bcd156db9601aef8d68f58fd1f26ebcd4a5e48af062"}
