Abramsky and Brandenburger used sheaf theory to give a general treatment of contextuality in quantum theory [New Journal of Physics 13 (2011) 113036]. However, contextual phenomena are found in other fields as well, for example database theory. In this paper, we shall develop this unified view of contextuality. We provide two main contributions: firstly, we expose a remarkable connection between contexuality and logical paradoxes; secondly, we show that","authors_text":"Kohei Kishida, Raymond Lal, Rui Soares Barbosa, Samson Abramsky, Shane Mansfield","cross_cats":["cs.LO","math.AT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2015-02-10T21:00:13Z","title":"Contextuality, Cohomology and Paradox"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1502.03097","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:c5376239fb3a2781fad999cd0cccf771e45d89def6e58ad329c3989d490e8cfb","target":"record","created_at":"2026-05-18T00:12:01Z","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":"5378e276f01adc8ccd53715d5ef920dc2d2b5fa11374bdd9e7a9b42710832ed4","cross_cats_sorted":["cs.LO","math.AT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2015-02-10T21:00:13Z","title_canon_sha256":"520846ecdcb710ce40b2664819c4b44bd52a8868020c1a5a10e262cfe9e0852e"},"schema_version":"1.0","source":{"id":"1502.03097","kind":"arxiv","version":2}},"canonical_sha256":"8d3908d9377d20a8b044c76057b52d3e00da0813317ff67176036eeb70a8e1df","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8d3908d9377d20a8b044c76057b52d3e00da0813317ff67176036eeb70a8e1df","first_computed_at":"2026-05-18T00:12:01.172182Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:12:01.172182Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pnthxGA+6LIKst01XTQwLa++rKcSWVz3KDsSMLbt6jIAoL5Fe9UldcnQFFy1gOg/5vK1MMGPx4RK75WJakXUDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:12:01.172703Z","signed_message":"canonical_sha256_bytes"},"source_id":"1502.03097","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c5376239fb3a2781fad999cd0cccf771e45d89def6e58ad329c3989d490e8cfb","sha256:65624023824feb54f9a3df3e9d98892a54d530362ba4fb7431ebe0fef3a7499c"],"state_sha256":"d785237db4ca695bb1ed19ca3d2d381aa71153656ca85096544391889782346e"}
