On the genus of the nating knot i

Webnating knot is both almost-alternating and toroidally alternating. Proposition 1. Let K be an alternating knot. Then K has an almost-alternating diagram and a toroidally alternating diagram. Proof. By [4], every alternating knot has an almost-alternating diagram. By [3], we can nd a toroidally alternating diagram from an almost-alternating diagram. Web13 de fev. de 2015 · The degree of the Alexander polynomial gives a bound on the genus, so we get 2 g ( T p, q) ≥ deg Δ T p, q = ( p − 1) ( q − 1). Since this lower bound agrees with the upper bound given by Seifert's algorithm, you're done. Here's another route: the standard picture of the torus knot is a positive braid, so applying Seifert's algorithm ...

WebThe first-order genus of a knot is difficult to compute, as there are many symplectic bases for a given Seifert surface. While difficult to compute in general, the first-order genus is a notion of higher-order genusdefinedforallknots.

Given a knot in the 3-sphere, the non-orientable 4-genus or 4-dimensional crosscap number of a knot is the minimal first Betti number of non-orientable surfaces, smoothly and properly embedded in the 4-ball, with boundary the knot. In this paper, we calculate the non-orientable 4 … WebIt is known that knot Floer homology detects the genus and Alexander polynomial of a knot. We investigate whether knot Floer homology of detects more structure of minimal genus Seifert surfaces for K. We de fine an invariant of algebraically slice, genus one knots and provide examples to show that knot Floer homology does not detect this invariant. ipc-s22fp-0360b-imou
