The Schrodinger spacetimes are regarded as null-like deformations of AdS_3. The original AdS_3 isometry SL(2,R)_L x SL(2,R)_R is broken to SL(2,R)_L x U(1)_R due to the deformation. According to this symmetry, there are two descriptions to describe the classical dynamics of the system, 1) the SL(2,R)_L description and 2) the enhanced U(1)_R description. In the former 1), we show that the Yangian symmetry is realized by improving the SL(2,R)_L Noether c","authors_text":"Io Kawaguchi, Kentaroh Yoshida","cross_cats":["math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2011-09-05T12:24:00Z","title":"Classical integrability of Schrodinger sigma models and q-deformed Poincare symmetry"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1109.0872","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":"sha256:466eb2d013e6e797e73397cd486cb7cfee9cf1cbb47f51f9caae87950131aee1","target":"record","created_at":"2026-05-18T02:00:39Z","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":"bab309c5060e4ced1da46a0f68cf9d0c06506ee4c5be28c0629c72c1d2020456","cross_cats_sorted":["math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2011-09-05T12:24:00Z","title_canon_sha256":"dfffec92f0f07999cc5852db9c1ef2d4e7bddaa0244b6e274a7d6b3ccc273083"},"schema_version":"1.0","source":{"id":"1109.0872","kind":"arxiv","version":2}},"canonical_sha256":"a80d653d912ecc840816132bc992851d3e460c85d58304a82e320b5b89acab36","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a80d653d912ecc840816132bc992851d3e460c85d58304a82e320b5b89acab36","first_computed_at":"2026-05-18T02:00:39.860060Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:00:39.860060Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RHDfOVWB+mE4frKp1frH9FiT1G3xFC+PGcn3URoTxvZO9rc3PUQmKa5yJ+bpzk4x3+sofwXUvQgesdX/WKNkCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:00:39.860793Z","signed_message":"canonical_sha256_bytes"},"source_id":"1109.0872","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:466eb2d013e6e797e73397cd486cb7cfee9cf1cbb47f51f9caae87950131aee1","sha256:1d46a6e73a8c10ace076d9ef41e2474d22bb9bbae2bf9eb6ee78c3f268e84fd8"],"state_sha256":"2307263cd0d7a4bad42a9b7c57e34c525ad6a7e15aa2ee2ede64e7ab6e06376f"}
