The most interesting conclusion is a kind of Mukai duality in which the \"dual abelian variety\" to a smooth projective genus-1 curve over R with no real points is (mildly) noncommutative.", "revisions": [ { "version": "v1", "updated": "2016-04-15T15:15:41.000Z" } ], "analyses": { "subjects": [ "14F05", "19E08", "19L64", "81T30", "14F22", "14H60", "14H81" ], "keywords": [ "algebraic k-theory", "derived equivalences", "dual abelian variety", "torus orientifold string theories", "real points" ], "tags": [ "conference paper" ], "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160404535R", "inspire": 1448125 } } }
