We give sufficient conditions for their restriction to the generic fiber to be semi-stable. We then apply the arithmetic analog of Bogomolov inequality in Arakelov theory, and deduce from it a lower bound for some successive minima in the lattice of extension classes between these line bundles.", "revisions": [ { "version": "v1", "updated": "2005-05-04T17:53:22.000Z" } ], "analyses": { "subjects": [ "14G40" ], "keywords": [ "arithmetic surface", "semi-stable extensions", "line bundle", "generic fiber", "extension classes" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......5079S" } } }
