These algebras are also shown to be embedded in different affine Kac-Moody algebras. In the three-dimensional case, we construct Chern-Simons actions invariant under these symmetries. This leads to a sequence of non-relativistic gravity theories, where the simplest examples correspond to extended Newton-Hooke and extended (post-)Newtonian gravity together with their C","authors_text":"Axel Kleinschmidt, Jakob Palmkvist, Joaquim Gomis, Patricio Salgado-Rebolledo","cross_cats":["gr-qc"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2019-12-16T18:26:51Z","title":"Newton-Hooke/Carrollian expansions of (A)dS and Chern-Simons gravity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1912.07564","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:a722d5c9befc85f95305fab473f6aaee61bb786905fb61fecf8134ee69698f23","target":"record","created_at":"2026-07-05T00:48:01Z","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":"680980ac3d7201db3df42ac48f1afa31333379fd0408e03bdf2862083a43668e","cross_cats_sorted":["gr-qc"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2019-12-16T18:26:51Z","title_canon_sha256":"000dd8acdbd1b162ad4c83259ee12392be8e8510f5ef91bb735091a9b78d049c"},"schema_version":"1.0","source":{"id":"1912.07564","kind":"arxiv","version":2}},"canonical_sha256":"1bb061b9f5ea7696b9f20f4753c223df1f12ccbbabb02359e1cf5fae555b1cb8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1bb061b9f5ea7696b9f20f4753c223df1f12ccbbabb02359e1cf5fae555b1cb8","first_computed_at":"2026-07-05T00:48:01.671548Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:48:01.671548Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WhQvh7JI7aPxQHz/deq5Lg74QBukUZkLR91GeEaG69h2O3/7kwO9mdI/aWpXI607RO1N/U+H+cAk2aGepKvzCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T00:48:01.671972Z","signed_message":"canonical_sha256_bytes"},"source_id":"1912.07564","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a722d5c9befc85f95305fab473f6aaee61bb786905fb61fecf8134ee69698f23","sha256:abe5792236ee9facd4aabe20986596a2f2b9b8aa0058fadbf4756706fd8ab9e8"],"state_sha256":"a13cd7cd5495c2b4ffd810ac1fd50ee675d5c9498d23eb142d768be2edd2d9a5"}
