In the present paper, we show that there exists a deformation of f which has only fold singularities and cusps as singularities of a real polynomial map from the plane to the plane. We then calculate the number of cusps of a deformation in a sufficiently small neighborhood of the origin.", "revisions": [ { "version": "v1", "updated": "2018-11-03T10:31:21.000Z" } ], "analyses": { "subjects": [ "57R45", "58K05", "58K60" ], "keywords": [ "complex polynomial", "deformation", "singularity", "real polynomial map", "sufficiently small neighborhood" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable" } } }
