A Dp-brane is a source for the Ramond-Ramond field strength G_(p+2), which can be thought of as the curvature of a connection on a p-gerbe with U(1)-band. The highest degree forms of the connection are the local Ramond-Ramond potentials C_(p+1). This picture is clear for p >= 0, a 0-gerbe being a line bundle. Actually, one can encounter also lower degree Ramond-Ramond field strengths: G_1 in IIB superstring theory, and G_0 in IIA s","authors_text":"Fabio Ferrari Ruffino","cross_cats":["math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-01-19T18:47:12Z","title":"Topics on the geometry of D-brane charges and Ramond-Ramond fields - Part II: Low-degree RR fields"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1201.4143","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":"sha256:7319a32fed6952261f69c7559c813c7c0a7f2cecc89436ae447444523c7a463d","target":"record","created_at":"2026-05-18T04:04:15Z","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":"eea6f1d0f22d4e1b895e9e364dc565bdee5d865ed733543aff375a5e3db2f6de","cross_cats_sorted":["math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-01-19T18:47:12Z","title_canon_sha256":"8596c4101df81336022f6ffaf669e05d20b9e280162586de4d76166d50af63e0"},"schema_version":"1.0","source":{"id":"1201.4143","kind":"arxiv","version":1}},"canonical_sha256":"95ac08eadaa7af048e6c89326ef300935acfd5f41ec4b2e459a299bb375bacc6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"95ac08eadaa7af048e6c89326ef300935acfd5f41ec4b2e459a299bb375bacc6","first_computed_at":"2026-05-18T04:04:15.824152Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:04:15.824152Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TBiXfl6aJC6ajRp6oTPuPlD3Q+doBJ9O0rhlaNech7B2Jje1lq61TYG0Edie27t+mwxsLm2CqyFGL1TQctcUAA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:04:15.824978Z","signed_message":"canonical_sha256_bytes"},"source_id":"1201.4143","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7319a32fed6952261f69c7559c813c7c0a7f2cecc89436ae447444523c7a463d","sha256:baa6ed280677dce587bae569539ebe3f2837d9b30776ed092173637d195c96fc"],"state_sha256":"3f1f0c17174b41373fb47ff2361f558cf5b788dd40711a4e3cbeefd3ef3d6b00"}
