One of them expresses $\\Delta^C$ in terms of dimensions of some factorspaces corresponding to a (multi-indexed) filtration on the ring ${\\cal O}_{C}$. The other one gives the coefficients of the Alexander polynomial $\\Delta^C$ as Euler characteristics of some explicitly described spaces (complements to arrangements of projective hyperplanes).", "revisions": [ { "version": "v1", "updated": "2000-02-07T18:16:29.000Z" } ], "analyses": { "subjects": [ "32S05", "14H20" ], "keywords": [ "plane curve singularity", "alexander polynomial", "analytic functions", "euler characteristics", "hyperplanes" ], "note": { "typesetting": "LaTeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2000math......2052C" } } }
