In the diffusive regime we find the same physical behavior as the one described by the diffusion equation on curved manifolds [J. Stat. Mech. (2010) P08006]. Therefore, we use the latter in order to analytically investigate the whole diffusive dynamics in compact geometries, namely, the circle and the sphere. Our findings are corroborated by means of Brownian dynamics computer simulations based on a heuristic adaptation of the Ermak-McCammon algorithm to the ","authors_text":"Jos\\'e Miguel M\\'endez-Alcaraz, Pavel Castro-Villarreal, Ram\\'on Casta\\~neda-Priego, Sendic Estrada-Jim\\'enez","cross_cats":["cond-mat.soft","math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2012-11-25T20:06:28Z","title":"Brownian motion of free particles on curved surfaces"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1211.5799","kind":"arxiv","version":2},"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:e13f2d2575b396ad6d7eb847ba893557c6efc8cf73dde7a70c61dec89f22066f","target":"record","created_at":"2026-05-18T03:21:21Z","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":"263664e01f8f995e02061e7a42e4f9662f8e8adb6cf5a45b46eb0f8c889cecf7","cross_cats_sorted":["cond-mat.soft","math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2012-11-25T20:06:28Z","title_canon_sha256":"6ad39f9b39858a0c42d9dc619cb18f049e21f71b2c5351cc2ae9e837249611d0"},"schema_version":"1.0","source":{"id":"1211.5799","kind":"arxiv","version":2}},"canonical_sha256":"08f082d5178328d6581399fa7ffb55b5e873ddfa4ae346aaa65e98dc9fc0fd63","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"08f082d5178328d6581399fa7ffb55b5e873ddfa4ae346aaa65e98dc9fc0fd63","first_computed_at":"2026-05-18T03:21:21.589449Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:21:21.589449Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1hXVJQFFHJGY+ytRYxazCo3nZG6VaynGrChS4iwMy89Ud5MIjEG+e8c8QVrgDM/bY3coi90w53JyQMRRqkuwAw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:21:21.589817Z","signed_message":"canonical_sha256_bytes"},"source_id":"1211.5799","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e13f2d2575b396ad6d7eb847ba893557c6efc8cf73dde7a70c61dec89f22066f","sha256:18e10ce111a56106c806610f1e4486695e039dac5e5c08ba0d515165c141e6fb"],"state_sha256":"15badad38fdd6328d9add148965a8065b0ab83c2db9632a74748ce994cdb79a8"}
