Furthermore, we give necessary and sufficient conditions for a spanned and big line bundle on a K3 surface to be birationally k-very ample and birationally k-spanned, and relate these concepts to the Clifford index and gonality of smooth curves in |L|.", "revisions": [ { "version": "v2", "updated": "2000-12-25T15:41:00.000Z" } ], "analyses": { "subjects": [ "14J28" ], "keywords": [ "k3 surface", "enriques surface", "kth-order embeddings", "sufficient conditions", "k-very ample" ], "note": { "typesetting": "TeX", "pages": 23, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2000math......8169L" } } }
