In contrast to fully-explicit schemes the time step does not depend on the physical parameters, removing the stiffness from the system. Furthermore, a wider class of collision operators (e.g. the Laplace-Beltrami operator) can be used. The derived scheme is applied to minimum-entropy models.","authors_text":"Florian Schneider","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.NA","submitted_at":"2016-11-04T10:34:38Z","title":"Implicit-explicit, realizability-preserving first-order scheme for moment models with Lipschitz-continuous source terms"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1611.01314","kind":"arxiv","version":1},"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":"sha256:26c281a221779c92d442ad7ef6501d82e68497d0509bfec631d32a7a72d7b799","target":"record","created_at":"2026-05-18T01:00:11Z","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":"82bf0af100b844fb2654284c6f30ee122413b481f37d994bb752170da25c2fe2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.NA","submitted_at":"2016-11-04T10:34:38Z","title_canon_sha256":"fc7bcb27dc6ecd30fc9b8c1b82e78353ebe2ba567ebd6419ab978e84b1f6dadb"},"schema_version":"1.0","source":{"id":"1611.01314","kind":"arxiv","version":1}},"canonical_sha256":"e6b7441254d2d59312dfbbaf5db96b3fa88a85326862715385b0705cbe66f471","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e6b7441254d2d59312dfbbaf5db96b3fa88a85326862715385b0705cbe66f471","first_computed_at":"2026-05-18T01:00:11.367708Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:00:11.367708Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IwFl9bzChfEMpbHlvx8eLh2ggbpzk8p55vFwNDOwOyN+1s9wwCWirXnp0YCr5lakmEomOjYpe2+351YQpUNzAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:00:11.368226Z","signed_message":"canonical_sha256_bytes"},"source_id":"1611.01314","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:26c281a221779c92d442ad7ef6501d82e68497d0509bfec631d32a7a72d7b799","sha256:a577bb2e75293d0db63ca4e3387722915291856291b7bde52446bdd7026f150f"],"state_sha256":"9b407dc18026c5fcc3583b2bfdc69ecb1be93a11bc12c702aa3a68ac4bfe2b4a"}
