TitleThe first rational Chebyshev knots
Author(s) P.-V. Koseleff, D. Pecker, Fabrice Rouillier
TypeArticle in Journal
AbstractA Chebyshev knot C ( a , b , c , φ ) is a knot which has a parametrization of the form x ( t ) = T_a ( t ) ; y ( t ) = T_b ( t ) ; z ( t ) = T_c ( t + φ ) , where a , b , c are integers, T n ( t ) is the Chebyshev polynomial of degree n and φ ∈ R . We show that any rational knot is a Chebyshev knot with a = 3 and also with a = 4 . For every a , b , c integers ( a = 3 , 4 and a , b coprime), we describe an algorithm that gives all Chebyshev knots C ( a , b , c , φ ) . We deduce the list of minimal Chebyshev representations of rational knots with 10 or fewer crossings.
