We construct compactifications of U in products of Hilbert schemes. Our approach generalizes and unifies classical constructions by Schubert-Semple, Le Barz-Keel, Kleiman and Cheah. An extensive study is done in the case n<4. This includes in particular a complete classification and a description of the quotients by the natural actions.", "revisions": [ { "version": "v1", "updated": "2001-07-05T16:41:28.000Z" } ], "analyses": { "subjects": [ "14C05" ], "keywords": [ "hilbert schemes", "configuration spaces", "natural actions", "construct compactifications", "approach generalizes" ], "note": { "typesetting": "TeX", "pages": 34, "language": "fr", "license": "arXiv", "status": "editable", "adsabs": "2001math......7041E" } } }
