The proof-term language of HA + EM1 consists in the lambda calculus plus an operator ||_a which represents, from the viewpoint of programming, an exception operator with a delimited scope, and from the viewpoint of logic, a restricted version of the excluded middle. We give a strong normalization proof for the system based on a technique of \"non-deterministic immersion\".","authors_text":"Federico Aschieri (ENS de Lyon, Universit\\'e de Lyon)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2013-09-05T08:03:19Z","title":"Strong Normalization for HA + EM1 by Non-Deterministic Choice"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1309.1254","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":"sha256:0c8da86db2eb2a5624edea19c763be0f91ec759633b9fa67b8ee106c0d6d79ea","target":"record","created_at":"2026-05-18T03:14:07Z","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":"76955676027084e26f4638f0c72140caae708f057fa7a61efe8e2a7cef46374f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2013-09-05T08:03:19Z","title_canon_sha256":"e567049f9ed80786befe0897b53066c25a66e4e3b331f85089c323b6b5520aa7"},"schema_version":"1.0","source":{"id":"1309.1254","kind":"arxiv","version":1}},"canonical_sha256":"182f82c973416310098bef69adbb568305f15350da46732760c0e012f8d920e4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"182f82c973416310098bef69adbb568305f15350da46732760c0e012f8d920e4","first_computed_at":"2026-05-18T03:14:07.863180Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:14:07.863180Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XVLK/SAt7Uu4QvWFmfC/9BvxJEOLMjAsjisfdUlncpV79xNz2suLKrQD9xKUFsFXG3u0uhQu+MrZqI05n//EDw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:14:07.863686Z","signed_message":"canonical_sha256_bytes"},"source_id":"1309.1254","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0c8da86db2eb2a5624edea19c763be0f91ec759633b9fa67b8ee106c0d6d79ea","sha256:a65af958eb38bc5b5b0f5a0ef040a28c954a191bd60b1ee3556156a287ff7a60"],"state_sha256":"0acb6353c852e377993352cf61b0bf64d8f5ecbf68d866e601cc65509466a4e5"}
