LeBrun's self-dual metric with torus action. We explicitly determine all U(1)-subgroups of the torus for which one can obtain U(1)-equivariant deformation that do not preserve semi-free U(1)-action. This gives many new self-dual metrics with U(1)-action which are not conformally isometric to LeBrun metric. We also count the dimension of the moduli space of self-dual metrics with U(1)-action obtained in this way.", "revisions": [ { "version": "v1", "updated": "2005-04-04T02:20:37.000Z" } ], "analyses": { "subjects": [ "53C25" ], "keywords": [ "lebruns self-dual metric", "torus action", "equivariant deformations", "preserve semi-free", "lebrun metric" ], "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......4047H" } } }
