In more recent times low-dimensional models (e.g. chiral models, factorizing models) often have been treated by special recipes in a way which sometimes led to a loss of unity of QFT. In the present work I try to counteract this apartheid tendency by reviewing past results within the setting of the general principles of QFT. To this I add two new ideas: (1) a modular interpretation of the chiral model Diff(S)-covariance with a close connection ","authors_text":"Bert Schroer","cross_cats":["cond-mat.stat-mech","gr-qc","math-ph","math.MP","physics.hist-ph","quant-ph"],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"2005-04-26T14:44:31Z","title":"Two-dimensional models as testing ground for principles and concepts of local quantum physics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/0504206","kind":"arxiv","version":4},"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:a2c8d61207642585ce242d8d56d7576a0a022786a049feae4b465718480b48ee","target":"record","created_at":"2026-05-18T01:05:57Z","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":"16382acd7c06c8222f302c780491b51ae30a13f5ee72fa29a598a2a5ac4c5ba5","cross_cats_sorted":["cond-mat.stat-mech","gr-qc","math-ph","math.MP","physics.hist-ph","quant-ph"],"license":"","primary_cat":"hep-th","submitted_at":"2005-04-26T14:44:31Z","title_canon_sha256":"33f27d101f8c8b57c71cccea6386f7681d41b3240215f76cc36a86478c9b24fa"},"schema_version":"1.0","source":{"id":"hep-th/0504206","kind":"arxiv","version":4}},"canonical_sha256":"c7ec313905443f8fde7a4d451c03cb612f4e1662e5e29efaa4ccd60547772165","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c7ec313905443f8fde7a4d451c03cb612f4e1662e5e29efaa4ccd60547772165","first_computed_at":"2026-05-18T01:05:57.004161Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:05:57.004161Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TbDjt/eMpYePJtBeXn5ySiBJNaljoe+cgkrpIhxOZv9tsMsc4HkSEE2TMzpjA4NkKAwr8Vesnb/FkwHuYkuaCA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:05:57.004763Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/0504206","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a2c8d61207642585ce242d8d56d7576a0a022786a049feae4b465718480b48ee","sha256:fdc5e0cdef0e521e2fa654f737f05a48839ac1a46eaca54f27ef53a34ce37e10"],"state_sha256":"e8e8740f54c054631622cf8357d0c4b76fabfca43f6cc906f93c2d70d557e070"}
