We identify a limit in which the entire string dynamics is described by a minimally coupled (supersymmetric) gauge theory on a noncommutative space, and discuss the corrections away from this limit. Our analysis leads us to an equivalence between ordinary gauge fields and noncommutative gauge fields, which is realized by a change of variables that can be described explicitly. This change of variables is checked by comparing the ordinary Dirac-Born-Infeld theory with its noncommutative counterpart. We obtain a new perspective on noncommutative gauge theory on a torus, its T-duality, and Morita equivalence. We also discuss the D0/D4 system, the relation to M-theory in DLCQ, and a possible noncommutative version of the six-dimensional (2,0) theory.","external_url":"https://arxiv.org/abs/hep-th/9908142","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-25T04:15:20.474798+00:00","pith_arxiv_id":"hep-th/9908142","created_at":"2026-05-10T14:30:30.907520+00:00","updated_at":"2026-05-25T04:15:20.474798+00:00","title_quality_ok":true,"display_title":"String theory and noncommutative geometry","render_title":"String theory and noncommutative geometry"},"hub":{"state":{"work_id":"cd06276f-e880-47e0-a69b-b341c888e534","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":16,"external_cited_by_count":null,"distinct_field_count":4,"first_pith_cited_at":"2019-07-14T20:50:37+00:00","last_pith_cited_at":"2026-05-22T17:20:58+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-05-27T19:17:54.088417+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":6}],"polarity_counts":[{"context_polarity":"background","n":6}],"runs":{},"summary":{},"graph":{},"authors":[]}}
