Via this relationship, we construct a stable pair compactification of the moduli space of anti-canonically polarized degree one del Pezzo surfaces.", "revisions": [ { "version": "v1", "updated": "2018-02-02T18:56:52.000Z" } ], "analyses": { "keywords": [ "del pezzo surface", "stable pair compactification", "moduli space", "elliptic fibrations", "rational elliptic surface" ], "note": { "typesetting": "TeX", "pages": 30, "language": "en", "license": "arXiv", "status": "editable" } } }
