We further demonstrate that correlation functions in two dimensional Liouville/Toda CFT compute the S^2 partition function for a class of N=(2,2) gauge theories, thereby uncovering novel modular properties in two dimensional gauge theories. Some of these gauge theories flow in the infrared to Calabi-Yau sigma models - such as the conifold - and the topology changing flop transition is realized as crossing symmetry in Liouville/Toda CFT. Evidence for Seiberg duality in two dimensions is exhibited by demonstrating that the partition function of conjectured Seiberg dual pairs are the same.", "revisions": [ { "version": "v3", "updated": "2014-01-07T01:53:40.000Z", "comment": "78 pages, LaTeX; v2: small corrections and references added; v3: JHEP version, discussing factorization further in new appendix F" }, { "version": "v4", "updated": "2016-11-12T03:08:51.000Z" } ], "analyses": { "keywords": [ "supersymmetric gauge theories", "exact results", "partition function", "conjectured seiberg dual pairs", "topology changing flop transition" ], "tags": [ "journal article" ], "publication": { "publisher": "Springer", "journal": "J.
