Following a Weighted Essentially Non-Oscillatory (WENO)-type paradigm, the proposed slope-limiter seeks to reconstruct smooth, non-oscillatory piecewise polynomial profiles as a non-linear combination of the natural and monotone-limited PPM and PQM interpolants. Compared to existing monotone slope-limiting techniques, this new strategy is designed to improve accuracy at smooth extrema, while controlling spurious oscillations in the neighbourhood of sharp feat","authors_text":"Darren Engwirda, Maxwell Kelley","cross_cats":["math.NA","physics.ao-ph","physics.flu-dyn"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.comp-ph","submitted_at":"2016-06-27T10:03:50Z","title":"A WENO-type slope-limiter for a family of piecewise polynomial methods"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1606.08188","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:f7272b3f9966827e8d0967db99b0a9fe54314171ec7b871d779d1b16fa90f920","target":"record","created_at":"2026-05-18T01:11:52Z","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":"e91b43c9875f0552883206ecd279ff7f707a367750353b50c7aec707afbc6851","cross_cats_sorted":["math.NA","physics.ao-ph","physics.flu-dyn"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.comp-ph","submitted_at":"2016-06-27T10:03:50Z","title_canon_sha256":"90bb83f87e0a01364cd4b77672dd38656a171e54d6ee812136810f24d8883707"},"schema_version":"1.0","source":{"id":"1606.08188","kind":"arxiv","version":1}},"canonical_sha256":"bd029ca191e5b3d653a0bf1f3fef562f36df7da0fdd0cea9625b5c81d5c91203","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bd029ca191e5b3d653a0bf1f3fef562f36df7da0fdd0cea9625b5c81d5c91203","first_computed_at":"2026-05-18T01:11:52.610258Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:11:52.610258Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QOo80gqIlWhHn8q58RiwoZ7M0nmlv0BK0tj4J0WfIx2dBIwMpVwCjdNZsTkw2wYkNY+eLiJcGRAFuPjvQni0DA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:11:52.610601Z","signed_message":"canonical_sha256_bytes"},"source_id":"1606.08188","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f7272b3f9966827e8d0967db99b0a9fe54314171ec7b871d779d1b16fa90f920","sha256:9dabb024e02f372cb89ee4d9ddeb466068975e05ba3874149798b4a7faaa3156"],"state_sha256":"c8427dacd31f10e962664f961543e96308255530bc37f934b1f765c01d6f84b5"}
