The proof follows the general lines of the proof given in 'The Geometry of Algebraic Curves'. What is different is that it uses Hopf's theorem to simplify the proof and strengthen the conclusions of the theorem.", "revisions": [ { "version": "v1", "updated": "2016-06-12T01:41:18.000Z" } ], "analyses": { "keywords": [ "shorter proof", "hopfs theorem", "general lines", "algebraic curves", "smooth curve" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
