WebJan 1, 1981 · Thus the first coefficient of the Conway polynomial determines the Arf invariant. (6) Knots of polynomial equal to one Let K C S3 be a knot, and associate to K the tangle T(K) obtained by taking oppositely oriented parallel strands as in Fig. 8. This tangle has trivial denominator. Its numerator is a (twisted) double of K. WebWe demonstrate that the Conway knot is not slice. This completes the classification of slice knots under 13 crossings and gives the first example of a non-slice knot which is both topologically slice and a positive mutant of a slice knot.

WebMay 27, 2024 · Conway’s knot, a famous mathematical problem, was a tricky one to untangle. Mathematicians have been arguing about how to solve it for more than 50 … WebMay 9, 2024 · A knot being 'slice' means that it does, and is 'non-slice' if it does not. In particular, Lisa Piccirillo showed that the Conway knot is not slice, so does not bound a nicely embedded disk. Why this is a 'useful' result is up to opinion. But there is a lot of study in geometric topology surrounding whether certain things bound other things. kentwood adult education centre penge

WebIn knot theory, Conway notation, invented by John Horton Conway, is a way of describing knots that makes many of their properties clear. It composes a knot using certain operations on tangles to construct it. Basic concepts [ edit] Tangles [ edit] In Conway notation, the tangles are generally algebraic 2-tangles.
