Asymptotically we prove that $N<\\sim{17/11}b_1(C)$ for large $b_1$. In particular, in the case of curves with one place at infinity, we confirm the Zaidenberg and Lin conjecture stating that $N\\le 2b_1+1$.", "revisions": [ { "version": "v1", "updated": "2009-08-31T10:49:12.000Z" } ], "analyses": { "subjects": [ "14H50", "14H20", "32S50", "14E15" ], "keywords": [ "singular points", "first betti number", "plane algebraic curve", "maximal number", "lin conjecture" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0908.4500B" } } }
