By solving Volin's algebraic equations for the perturbative coefficients we study the large order asymptotic behaviour of the perturbative series analytically. We confirm the previously numerically found leading behaviour and study the nearest singularities of the Borel transformed series and the associated alien derivatives. We find a 'resurgence' behaviour: the leading alien derivatives can be express","authors_text":"Istv\\'an Vona, J\\'anos Balog, Zolt\\'an Bajnok","cross_cats":["math-ph","math.MP"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"hep-th","submitted_at":"2021-11-30T13:33:41Z","title":"Analytic resurgence in the O(4) model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2111.15390","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":"sha256:0a42dc8e09881acc369ba24caa2e682852ace90b599f0aa881bf54631be35c89","target":"record","created_at":"2026-07-05T04:18:04Z","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":"4a9e7fddc1c454ec632551bf273a9736e0a714da7f85952a83764efe8cd857da","cross_cats_sorted":["math-ph","math.MP"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"hep-th","submitted_at":"2021-11-30T13:33:41Z","title_canon_sha256":"575597a6df784477764edfce78dc36128bd5ee287029862cb0e9b62b4483f716"},"schema_version":"1.0","source":{"id":"2111.15390","kind":"arxiv","version":1}},"canonical_sha256":"5773c72f48735cd6a454cb79cc17b25b828c12b5f232c46c2f8f99ececd86068","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5773c72f48735cd6a454cb79cc17b25b828c12b5f232c46c2f8f99ececd86068","first_computed_at":"2026-07-05T04:18:04.286166Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:18:04.286166Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xHtzFp4qQvDXS8vvuEQHDXrk6yjA6tm1BNp5E8ogxA5pXUL3EuhZsgeZy6/R4X6RErGRDAn7rtJuiIK6NRyJCA==","signature_status":"signed_v1","signed_at":"2026-07-05T04:18:04.286635Z","signed_message":"canonical_sha256_bytes"},"source_id":"2111.15390","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0a42dc8e09881acc369ba24caa2e682852ace90b599f0aa881bf54631be35c89","sha256:6642b035011c32eb0a6f8ca2c5c0f1a81007360902afa193ab51bf9a655ffe71"],"state_sha256":"994c4e884e53a195dc367b3b436566baf71be54573bb68c665cf32ae415c8bdf"}
