We show that the duality breaks down, and then go on to discuss a sense in which general relativity, formulated using non-Hausdorff manifolds, exhibits excess structure when compared to Einstein algebras. We discuss how these results bear on a class of algebraically-motivated deflationist views about spacetime ontology. We conclude with a conjecture concerning non-Hausdorff spacetimes with no bifurcate curves.","authors_text":"James Owen Weatherall, Jingyi Wu","cross_cats":["gr-qc","math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.hist-ph","submitted_at":"2023-05-05T22:59:33Z","title":"Between a Stone and a Hausdorff Space"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2305.03871","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":"sha256:3672766df17cd85f9882c4eddf3070b8c1ea612753fee8cdbe0f9d3095498654","target":"record","created_at":"2026-07-05T07:03:23Z","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":"45e05cff24d6717cd8a95b7e7f3307890098ed1df7e83e21c0b40946dacbbb26","cross_cats_sorted":["gr-qc","math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.hist-ph","submitted_at":"2023-05-05T22:59:33Z","title_canon_sha256":"9424beb6f87e994609f3d050da21719f65450e2d148e60f22714b8acc40a2070"},"schema_version":"1.0","source":{"id":"2305.03871","kind":"arxiv","version":2}},"canonical_sha256":"9d4ee869f3df57a266c79f914dd712e94c6f8ff6f1a2521b2ebbf3cddb83ddaf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9d4ee869f3df57a266c79f914dd712e94c6f8ff6f1a2521b2ebbf3cddb83ddaf","first_computed_at":"2026-07-05T07:03:23.957421Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:03:23.957421Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Ljkegft1LBLs6q53u7UbjW+Z9OzU5IfToPKKNFbdnvJoZbG8+FC1npqXkVml0/rl1mKc2RDtksnGmjE1oagJAg==","signature_status":"signed_v1","signed_at":"2026-07-05T07:03:23.957930Z","signed_message":"canonical_sha256_bytes"},"source_id":"2305.03871","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3672766df17cd85f9882c4eddf3070b8c1ea612753fee8cdbe0f9d3095498654","sha256:efc88ea7ab910ddec4e7884f0d22a14a883048ae293d284b9b9f51d075fc80b8"],"state_sha256":"9b287768328928cac5eb5754b42ff83722b675e9ca15b902ae55eecc01cae743"}
