We use Monge-Amp\\`ere equations to give a classification of the surfaces in 3-dimensional space forms which are embedded around a non-removable isolated singularity and have a prescribed, real analytic, positive extrinsic curvature function at every point. Specifically, we prove that this space is in one-to-one correspondence with the space of regular, analytic, strictly convex Jordan curves in the 2-dimensional sphere $\\mathbb{S^2}$.", "revisions": [ { "version": "v1", "updated": "2014-11-11T18:00:15.000Z" } ], "analyses": { "subjects": [ "35J96", "53C42" ], "keywords": [ "warped product", "monge-ampère equations", "non-removable isolated singularity", "positive extrinsic curvature function", "strictly convex jordan curves" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1411.2904G" } } }
