Such systems can be efficiently treated by a class of implicit-explicit (IMEX) diagonally implicit multistage integration methods (DIMSIMs), where the stiff part is integrated by implicit formula, and the non-stiff part is integrated by an explicit formula. We will construct methods where the explicit part has strong stability preserving (SSP) property, and the i","authors_text":"Giuseppe Izzo, Zdzislaw Jackiewicz","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.NA","submitted_at":"2018-06-20T15:47:21Z","title":"Transformed implicit-explicit DIMSIMs with strong stability preserving explicit part"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.07804","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":"sha256:5bc4229b1743a689d7d7e7b45c23a50bb3194463175f854e06c87ba3ccb20517","target":"record","created_at":"2026-05-18T00:01:32Z","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":"e57373f9a3e5f6a8b8ef8a72ad5a7740144db8b90ce7f5ff669e56e92d61f896","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.NA","submitted_at":"2018-06-20T15:47:21Z","title_canon_sha256":"eb7c7ced0c7d8e5cb1a9c99d5dd409b49748de53422318475770f42dda7b9290"},"schema_version":"1.0","source":{"id":"1806.07804","kind":"arxiv","version":2}},"canonical_sha256":"dfa0af15e04d5cf8a134740ef05a67222f0c7cf75fa6be084ac64f0ea53bdd88","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dfa0af15e04d5cf8a134740ef05a67222f0c7cf75fa6be084ac64f0ea53bdd88","first_computed_at":"2026-05-18T00:01:32.757791Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:01:32.757791Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"O9Omd+jbmmgFcJv4694RXKDOjqJfoiF2DdWhXQDsCUch4bZee6TaJiJtqRcojv2O8PmqJpSdYgDHPpIoKSbFAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:01:32.758278Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.07804","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5bc4229b1743a689d7d7e7b45c23a50bb3194463175f854e06c87ba3ccb20517","sha256:8b56f39fb8f6a2a05d33da160f8cc4094a1b05db7725a5c9230339ea1e65fda1"],"state_sha256":"c146369b36b0dbee63a40fb4eb51534c4bcf763f9ca28cc4c5a736aaec9f5289"}
