We consider massless electrons, with a charge density following a Maxwell-Boltzmann law. For cold ions, using the relative entropy method, we derive the classical Isothermal Euler or the (inviscid) Shallow Water systems from fluid mechanics. In a second time, we study the combined quasineutral and strong magnetic field regime for such plasmas.","authors_text":"Daniel Han-Kwan (DMA)","cross_cats":["math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.AP","submitted_at":"2010-04-06T19:03:29Z","title":"Quasineutral limit of the Vlasov-Poisson system with massless electrons"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1004.0932","kind":"arxiv","version":3},"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":"sha256:298d6d2564f8a441bee7fbb352c90dca8e8eb1a74f106e53ca1b8f82a77d09da","target":"record","created_at":"2026-05-18T04:34:37Z","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":"6242cd96acc51f0b452e78d3c539eeb9b0e99f984bb918fe9df6fe50e4e02c31","cross_cats_sorted":["math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.AP","submitted_at":"2010-04-06T19:03:29Z","title_canon_sha256":"ac7398aa21ae5d45e8bff7cbc0cfbd69e40dbfe73e95ede2c849dd9cf19e4661"},"schema_version":"1.0","source":{"id":"1004.0932","kind":"arxiv","version":3}},"canonical_sha256":"ea99369704817f4907effe2cd019b57f8a3c7cf8c007da4fb4f71cb255970b71","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ea99369704817f4907effe2cd019b57f8a3c7cf8c007da4fb4f71cb255970b71","first_computed_at":"2026-05-18T04:34:37.161901Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:34:37.161901Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"mMPIRaWV49un0tgGzo0y1JyTbunN2YZhn6Kndygv2nHJo4EiYuLHjg8Ck5IWFaOEHHUR0XdQPWelcc7R4IX7Dg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:34:37.162298Z","signed_message":"canonical_sha256_bytes"},"source_id":"1004.0932","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:298d6d2564f8a441bee7fbb352c90dca8e8eb1a74f106e53ca1b8f82a77d09da","sha256:ca37fe4ad63e5c0341ed0d733eec3a47ab82d43d257ada58f0142f080c9ab83b"],"state_sha256":"3b6da9a9b44ba8d372aed3b2e590b5ac4c7db22bcd7d6f2982ea1f538fdd5b0f"}
