We say that $\\alpha$ is a slant helix if its principal normal vector $N$ makes a constant angle with a fixed direction $U$. In this work we give different characterizations of such curves in terms of their curvatures.", "revisions": [ { "version": "v1", "updated": "2009-01-21T17:42:34.000Z" } ], "analyses": { "subjects": [ "53C40", "53C50" ], "keywords": [ "slant helices", "euclidean four-dimensional space", "principal normal vector", "slant helix", "constant angle" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable" } } }
