In particular the mass can be calculated exactly on a sphere inside the cosmological horizon. The formalism requires varying the background metric solution by a perturbation that satisfies the linearized equations of motion but need not share the Killing symmetry of the solution and is therefore ideally suited to calculating masses in stationary space-times perturbed by a ","authors_text":"Brian P Dolan","cross_cats":["hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2018-08-28T01:25:20Z","title":"The definition of mass in asymptotically de Sitter space-times"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.09081","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:f5bc3a29908c97ec816c526777ed9b0b2b5c4c746b5b20371a62fcc463f523b9","target":"record","created_at":"2026-05-17T23:50:12Z","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":"5e649198250d74eaaaf1483ee18f55a7300ea77fb3b56ec8c413f24f0b5bcc8d","cross_cats_sorted":["hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2018-08-28T01:25:20Z","title_canon_sha256":"775fb232e9836c4a836bc811fb8337bfd0eda1086e11dbd96151cabdcbc215fb"},"schema_version":"1.0","source":{"id":"1808.09081","kind":"arxiv","version":1}},"canonical_sha256":"71555971cdf9ba768f11bc2ad7025d2f915a7fd76ec5d32266e45bf4413dc667","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"71555971cdf9ba768f11bc2ad7025d2f915a7fd76ec5d32266e45bf4413dc667","first_computed_at":"2026-05-17T23:50:12.700992Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:50:12.700992Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Pkq0AQpZOAPDX5w5qMl2PEmgRU0wNGtPNno5qeXN1qbfatczPjxmp5BIc0iAKmxAPzWYVU4yhKBQymgYbUVkDg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:50:12.701383Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.09081","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f5bc3a29908c97ec816c526777ed9b0b2b5c4c746b5b20371a62fcc463f523b9","sha256:49436e6098d6aebfa01db09e1f0f57509117516c638f8270fb415a13cfed5f22"],"state_sha256":"38f6e4c5a5d1164d37f1ea50d2dc3c1d1da3d7585af4af721f7287a88416c711"}
