First, we prove that the complex is exact in degree one under suitable conditions on the underlying topological space, but that exactness in general depends on the complex structure. Second, we show exactness in high degrees for holomorphically contractible spaces under mild assumptions on the nature of singularities, e.g. klt singularities.\n  Subsequently, the exactness of the de Rham complex of reflexive differential forms is related to the Lipman-Zariski conject","authors_text":"Clemens J\\\"order","cross_cats":["math.CV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.AG","submitted_at":"2014-01-29T12:43:26Z","title":"On the Poincar\\'e Lemma for reflexive differential forms"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1401.7495","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:a11a49d7f1cdbc17ac0f7ac4d30b93b1ec3e8ff64ebd9ea6166a209cf46bf3c4","target":"record","created_at":"2026-05-18T03:00:48Z","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":"2740f387a6ea506b6e81141cf37519f927a5afa22a549fdf647d71502df03186","cross_cats_sorted":["math.CV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.AG","submitted_at":"2014-01-29T12:43:26Z","title_canon_sha256":"f77ecd6f1e074521eb6694e95b62346b7b4e43f97545ee1bb08539f59fb747f0"},"schema_version":"1.0","source":{"id":"1401.7495","kind":"arxiv","version":1}},"canonical_sha256":"1a3265a786f44a651dbc4ca30474c375d9e791f08196ba88e47ba1c678114486","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1a3265a786f44a651dbc4ca30474c375d9e791f08196ba88e47ba1c678114486","first_computed_at":"2026-05-18T03:00:48.190160Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:00:48.190160Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ynyNQ1l+k8xGcHeA1akTAxrEFwdW8ryHQpQSLJt4VMaObU5CFlQWql/wU+n32D/KMqNDp8knN6RtA4frD8fxDA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:00:48.190745Z","signed_message":"canonical_sha256_bytes"},"source_id":"1401.7495","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a11a49d7f1cdbc17ac0f7ac4d30b93b1ec3e8ff64ebd9ea6166a209cf46bf3c4","sha256:93793bff83e253568d431ed1cc0020d826f0114631a62213e4a0c2f70128bf0a"],"state_sha256":"93f499e5f81c7aab1911ea137e80df5a669134bad6d96bd2f7185942f067173d"}
