These objects are: the affine critical values, the affine Milnor numbers for all irregular fibers, the critical values at infinity, and the Milnor numbers at infinity for all irregular fibers. Then for a family of polynomials we detect parameters where the topology of the polynomials can change. Implementation and examples are given with the computer algebra system Singular.", "revisions": [ { "version": "v1", "updated": "2003-09-19T12:50:58.000Z" } ], "analyses": { "keywords": [ "computation", "computer algebra system singular", "irregular fibers", "affine milnor numbers", "detect parameters" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2003math......9322B" } } }
