If the singularity is of type $A_{2k+1}$, under the condition $d<(k+5)/2$, a classification of such hypersurfaces upto homeomorphism (which is diffeomorphism on the nonsingular part) is obtained. As an application, cubic hypersurfaces with an $A_5$-singularity are constructed.", "revisions": [ { "version": "v1", "updated": "2006-09-19T12:14:33.000Z" } ], "analyses": { "keywords": [ "classification", "hypersurfaces upto homeomorphism", "singular hypersurfaces", "nonsingular part", "cubic hypersurfaces" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006math......9523S" } } }
