In this paper, we show that every regular function, either on finite words or on infinite words, captured by a deterministic two-way transducer, can be described with a regular transducer expression (RTE). For infinite words, the transducer uses Muller acceptance and $\\omega$-regular look-ahead. \\RTEs are constructed from constant functions using the combinators if-then-else (deterministic choice), Hadamard product, and unambiguous versions o","authors_text":"Krishna Shankara Narayanan, Paul Gastin, Vrunda Dave","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.FL","submitted_at":"2018-02-05T16:55:48Z","title":"Regular Transducer Expressions for Regular Transformations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.02094","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:e1cc38052196575d6a5acf084c6b611b90fa6dbaa20a260d1cafc5d029b17329","target":"record","created_at":"2026-05-18T00:24:10Z","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":"02a6ed577f4c3999d9f1caa1ec1706f309bd0b10cd6947391821559e0022c6cb","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.FL","submitted_at":"2018-02-05T16:55:48Z","title_canon_sha256":"7f3cf013a948cd491c3870f2897355ec92ed726c779c551a87d13bd48a1efbc1"},"schema_version":"1.0","source":{"id":"1802.02094","kind":"arxiv","version":1}},"canonical_sha256":"2a30fb3c3638676fa71900b48dd7cc807e275dcaeee81796b9769e90757000f8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2a30fb3c3638676fa71900b48dd7cc807e275dcaeee81796b9769e90757000f8","first_computed_at":"2026-05-18T00:24:10.904850Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:24:10.904850Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"weeUhbZKqdKf3hGNO/KudgRaeiQjInZtcFhYvkP3emcAav/c7BESzM1BKzaRu9a/HnTGWnN/f8wMO9w4GvDmCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:24:10.905415Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.02094","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e1cc38052196575d6a5acf084c6b611b90fa6dbaa20a260d1cafc5d029b17329","sha256:12bce0629ded1b2ff2ef76b4508818ba1864e33b0cd1dd8bfa137569d47af22a"],"state_sha256":"6abe5b67d66384071aefe753bf39d5e4b8af280b357954dd871434c5c66f4f1e"}
