We consider weakly nonlinear perturbations of space-periodic steady convective magnetic dynamos in a rotating layer that were identified in our previous work. The perturbations have a spatial scale in the horizontal direction that is much larger than the period of the perturbed convective magnetohydrodynamic state. Following the formalism of the multiscale stability theory, we have derived the system of amplitude equations governing the evolution of the leading","authors_text":"Roman Chertovskih, Vladislav Zheligovsky","cross_cats":["math.NA","nlin.CD"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2015-04-26T17:42:22Z","title":"Large-scale weakly nonlinear perturbations of convective magnetic dynamos in a rotating layer"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1504.06856","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":"sha256:7ad76a76d733dde721f563c28603187b740280fe3121623806e3398454a1aeb5","target":"record","created_at":"2026-05-18T01:25:47Z","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":"1294326bc9dd004e96adcc8051db61f4dcf791a707784e036b72a03d03a13914","cross_cats_sorted":["math.NA","nlin.CD"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2015-04-26T17:42:22Z","title_canon_sha256":"052c775403811dde442c3a24725fb83e76083e0e57cfd51355e3905e1945ca8f"},"schema_version":"1.0","source":{"id":"1504.06856","kind":"arxiv","version":2}},"canonical_sha256":"2ceb7f28a4f80d3f2e7ee716dd888548b21b62ce2729516f2451878eb2c02708","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2ceb7f28a4f80d3f2e7ee716dd888548b21b62ce2729516f2451878eb2c02708","first_computed_at":"2026-05-18T01:25:47.107211Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:25:47.107211Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"g/o5LZehl5cHvvCbvX3+/1GnfARhYtHse81tWkg/s/ejdGUr6JaaCn3bwzGEcDuU+3u3Q0azFU06WSIsm436AA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:25:47.107610Z","signed_message":"canonical_sha256_bytes"},"source_id":"1504.06856","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7ad76a76d733dde721f563c28603187b740280fe3121623806e3398454a1aeb5","sha256:a6fdb5340982dbbc96b2d0da9cfe58ebccd6848dca6dc280b23f6d4ebe7ea9dd"],"state_sha256":"879cd3aac4571af26ffa60b69b767e8684441fcf655a7688dd6b57a6d99e5511"}
