The canonical nature might suggest that such modifications are guaranteed to preserve general covariance. Here, however, we show that a dedicated space-time analysis is still required, even in the case of a bijective canonical transformation. In addition, a complete global analysis is presented for a recent proposal of a non-bijective transformation, showing that it does not preserve general covariance and that the only novel physical effect introduced b","authors_text":"Martin Bojowald","cross_cats":["hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2021-02-22T15:58:08Z","title":"Non-covariance of \"covariant polymerization\" in models of loop quantum gravity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2102.11130","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":"sha256:45c747dfc8d0f1a2655d9245ddebc6ede8bf2270f551801671b0324dc54fa62d","target":"record","created_at":"2026-07-05T02:55:40Z","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":"8cefff94abd8b3d86c4cc750561d48ae4428f8a4ab83b84a6c851a147b06206c","cross_cats_sorted":["hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2021-02-22T15:58:08Z","title_canon_sha256":"268c90dc5aedc7fe7aa89b1e77198c47fb1564a32fb96e44b0b36b458232fb5c"},"schema_version":"1.0","source":{"id":"2102.11130","kind":"arxiv","version":2}},"canonical_sha256":"fb13591f3d88ee265a4e83de4a3a43c4c69c0e41ccc3ffa048cba07ec374ca9f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fb13591f3d88ee265a4e83de4a3a43c4c69c0e41ccc3ffa048cba07ec374ca9f","first_computed_at":"2026-07-05T02:55:40.572026Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:55:40.572026Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XnRIkBq/V/8CIVrPosKzD7J5YZetALssKvLvHotxwaa6nuFiAMZdUONyOj1X1v9+OyZ5iy1+wegtrN0nEt9bBQ==","signature_status":"signed_v1","signed_at":"2026-07-05T02:55:40.572527Z","signed_message":"canonical_sha256_bytes"},"source_id":"2102.11130","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:45c747dfc8d0f1a2655d9245ddebc6ede8bf2270f551801671b0324dc54fa62d","sha256:c67fc0b8666492d079d8948af9e1bd71a52b67b4eeb5d6093485733f85d383d4"],"state_sha256":"dc0897bcf25526aa1997649a4a29dc3be6bdc978baf39f69830299e0a8343c57"}
