Then a K\\\"ahler class contains a K\\\"ahler metric of constant scalar curvature if and only if the K\\\"ahler class is contained in the analytic subvariety. On examination of the analytic subvariety, it is shown that $M$ admits infinitely many nonhomothetic K\\\"ahler classes containing K\\\"ahler metrics of constant scalar curvature but does not admit any K\\\"ahler-Einstein metric.", "revisions": [ { "version": "v1", "updated": "2009-02-05T08:28:28.000Z" } ], "analyses": { "subjects": [ "53C25", "53C55" ], "keywords": [ "constant scalar curvature", "kähler metrics", "analytic subvariety", "compact complex fano manifolds", "bando-calabi-futaki character vanishes" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0902.0861T" } } }
