We show that two real algebraic knots of degree $\\leq5$ are rigidly isotopic if and only if their degrees and encomplexed writhes are equal. We also show that any irreducible smooth knot which admits a plane projection with less than or equal to four crossings has a rational parametrization of degree $\\leq 6$. Furthermore an explicit construction of rational knots of a given degree with arbitrary encomplexed writhe (subject to natural restrictions) is presented.", "revisions": [ { "version": "v2", "updated": "2011-08-05T13:48:31.000Z" } ], "analyses": { "keywords": [ "low degree", "study rational real algebraic knots", "arbitrary encomplexed writhe", "rational knots", "irreducible smooth knot" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 28, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0905.4186B" } } }
