The pseudo-energy serves as the Hamiltonian of the system, the action coordinates are the contribution of the interfacial waves to the wave-action, and the angles are their phases. The term \"generalized action-angle\" aims to emphasize that the action of each wave is generally time dependent and this allows instability. An attempt is made to relate this formalism to the action at a distance resonance instability mechanism between cou","authors_text":"Anirban Guha, Eyal Heifetz","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2017-03-08T21:11:49Z","title":"A generalized action-angle representation of wave interaction in stratified shear flows"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.03032","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":"sha256:632d63fac626e9e5ef71bba5e4805c64e7a3f5bc0f08d075e0aa55b5f610841a","target":"record","created_at":"2026-05-18T00:23:39Z","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":"c98cc82e275f727bf30962649ee884655ad2415e0fe7e0d33bb613ef0ff0a54e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2017-03-08T21:11:49Z","title_canon_sha256":"b6142f99dea4397f3cd99dc4900b08b4c1f4f0031926d428bd5d55eab88aeae1"},"schema_version":"1.0","source":{"id":"1703.03032","kind":"arxiv","version":2}},"canonical_sha256":"cb98053254f129b5691a947419a2ebdec3d3adbd280898cf880ac44e1af1a20b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cb98053254f129b5691a947419a2ebdec3d3adbd280898cf880ac44e1af1a20b","first_computed_at":"2026-05-18T00:23:39.821071Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:23:39.821071Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"inDLNIhE+uFS3pMbvIphoe7YUaCDFycWJtUFUiHJ1if9uqNkFj5gUid2wxMcr2c9Dx3YYtncunkorUUKj6mUDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:23:39.821785Z","signed_message":"canonical_sha256_bytes"},"source_id":"1703.03032","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:632d63fac626e9e5ef71bba5e4805c64e7a3f5bc0f08d075e0aa55b5f610841a","sha256:59d4af531f1f59bf35e4b29a345a818c9931eb38631846fc0e6d00ab8e6024a6"],"state_sha256":"e12107ab338804ab8c5da2852217a002ffe1637a78d1ad63340bf97970817120"}
