The critical dimension for this theory is $\\hat c= 2$ ($c=6$). It is shown that superstrings (in both the RNS and GS formulations) and critical $N=2$ strings are special cases of this topological theory. Applications for this new topological theory include: 1) Proving the vanishing to all orders of all scattering amplitudes for the self-dual $N=2$ string with flat background, with the exception of the three-point function and the closed-string partition function; 2) Showing that the topological partit","authors_text":"Cumrun Vafa, Nathan Berkovits","cross_cats":[],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"1994-07-28T20:28:03Z","title":"N=4 Topological Strings"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/9407190","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":"sha256:9a50735802d93a300cd0663b35ede74b2b1305d65a834f5535efcf9bedbc64bb","target":"record","created_at":"2026-07-04T15:57:49Z","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":"c167bd81c61c345a1caeef0ecafd2a42e7173f66c3cd1afd51e23ab14fb730f4","cross_cats_sorted":[],"license":"","primary_cat":"hep-th","submitted_at":"1994-07-28T20:28:03Z","title_canon_sha256":"402a5237e8d84100fce1406d0735aecfa51625749d105ec4098a3108956a958c"},"schema_version":"1.0","source":{"id":"hep-th/9407190","kind":"arxiv","version":2}},"canonical_sha256":"1daa11f68f85f7865fd1aa3b22d01f48c6b335f626e2fe65d50321286c5daf6d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1daa11f68f85f7865fd1aa3b22d01f48c6b335f626e2fe65d50321286c5daf6d","first_computed_at":"2026-07-04T15:57:49.419042Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:57:49.419042Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"CRVk1Edz+cMuUnwQA2a5lp/Hmq36OSwJvJoaCvtFgOSLs43eS+068agtIEefii9GU+lib6obicJqVgxsVqozAg==","signature_status":"signed_v1","signed_at":"2026-07-04T15:57:49.419441Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/9407190","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9a50735802d93a300cd0663b35ede74b2b1305d65a834f5535efcf9bedbc64bb","sha256:da832eb1169c1d3351f4c10c5ca7be18d0006c0549b3e16d9334cf8495f93e8f"],"state_sha256":"3072dc898edc7429f4d51fa331f4faea4a06f3c73b6a0c9bd501016c4350e4b7"}
