We seek and find its relation to the Freed-Witten quantization of worldvolume fluxes on 7-branes in type IIB orientifold compactifications on Calabi-Yau threefolds. By explicitly constructing the appropriate four-cycles on which to calculate the periods of the second Chern class of the fourfolds, we find that there is a half-integral shift in the quantization of G-flux whenever the corresponding dual 7-brane is wrapped on a non-spi","authors_text":"Andres Collinucci, Raffaele Savelli","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-03-20T19:10:55Z","title":"On Flux Quantization in F-Theory II: Unitary and Symplectic Gauge Groups"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1203.4542","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":"sha256:3a92a4b856d7a5d502f172eddc206599e2de1e3a0b317d0edc50b70b45e5dc9c","target":"record","created_at":"2026-05-18T01:58:05Z","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":"e9964fc6fa4551e63d7d7fca99936c057d54c8f19ecd8c1639d0b33225adc1fb","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-03-20T19:10:55Z","title_canon_sha256":"3fe3b3a8a5fb2847d419a0495d79817001ccd1b879f457ed7788f77106a39627"},"schema_version":"1.0","source":{"id":"1203.4542","kind":"arxiv","version":1}},"canonical_sha256":"78bd20fd5d4a81c2f0a24b33295ef5d0a361b58932ec39f3d59fbd09f91ff774","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"78bd20fd5d4a81c2f0a24b33295ef5d0a361b58932ec39f3d59fbd09f91ff774","first_computed_at":"2026-05-18T01:58:05.332169Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:58:05.332169Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"MFxHR1XXvd5HzKJRA6H7q+O2nB3fts9bG9jELvRzGDGLIBoFCcJSl96VW2hYtx1pDo+Cup6dfl3DqJgYOlawCw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:58:05.332753Z","signed_message":"canonical_sha256_bytes"},"source_id":"1203.4542","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3a92a4b856d7a5d502f172eddc206599e2de1e3a0b317d0edc50b70b45e5dc9c","sha256:f992192e22dcff0676e6356ebb349e01783805aefa2396d4ba1ebfb8f046b824"],"state_sha256":"f2311a0b9705fd6025e09bae4f3fa03854decd0407c33805c22b51abb0097dfe"}
