We emphasize that whereas Kochen-Specker's is essentially a no-go theorem, Gleason's provides a mathematical justification of Born's rule. Our extracontextual approach requires however a way to describe the ``Heisenberg cut''. Following an article by John von Neumann on infinite tensor products, this can be done by noticing that the usual formalism of quantum mechanics, associated with unitary equivalence of representation","authors_text":"Mathias van den Bossche, Philippe Grangier","cross_cats":["physics.hist-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2023-04-16T12:06:44Z","title":"Revisiting Quantum Contextuality in an Algebraic Framework"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2304.07757","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":"sha256:5e00681c4a1e67359eabedc706dbb10dfb0ad994563d679df373dcfe5fa32b48","target":"record","created_at":"2026-07-05T06:01:24Z","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":"29914e522b23dd57d35ad68138f40756a35d6d455c6923b10c6fb2a2cff51d15","cross_cats_sorted":["physics.hist-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2023-04-16T12:06:44Z","title_canon_sha256":"31a81842ecd4ef215d4ba9634ee134911ba7e1034494e5050a1c84c7f6cb540c"},"schema_version":"1.0","source":{"id":"2304.07757","kind":"arxiv","version":1}},"canonical_sha256":"4cfd364be4ccf92735fec196f01ff8d88ad1b88794b61dcc597c2afb56f6b294","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4cfd364be4ccf92735fec196f01ff8d88ad1b88794b61dcc597c2afb56f6b294","first_computed_at":"2026-07-05T06:01:24.993518Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:01:24.993518Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BkkdHm0HVvBxkkHfh+Jjwzitsrx+nLEKl0a8jsu9DmN1j23UNsavve/bywOl+fqbmECZ2ERiEaCuk1GsfeDPAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T06:01:24.993921Z","signed_message":"canonical_sha256_bytes"},"source_id":"2304.07757","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5e00681c4a1e67359eabedc706dbb10dfb0ad994563d679df373dcfe5fa32b48","sha256:e35ff4f01860cc7ccffff3454de7ca64d3ac0aef4259bd5855f59997b8b94cca"],"state_sha256":"4d9c628626bb9c6cae42e23bc65e12b7772b13af3c40a02c178ed4cabfbf2ef3"}
