We say that Determining knot genus in a fixed 3-manifold M is the decision problem asking whether the genus of Kis equal to a given non-negative integer. Theorem 1.2. Let Mbe a compact, orientable 3-manifold given as above. The problem Determining knot genus in the fixed 3-manifold Mlies in NP. 1.1. Ingredients of the proof.

WebExample: An example of a knot is the Unknot, or just a closed loop with no crossings, similar to a circle that can be found in gure 1. Another example is the trefoil knot, which has three crossings and is a very popular knot. The trefoil knot can be found in gure 2.

In general position of planar diagrams of knots and links, two strands meet at every crossing. It is known since that any knot and every link has a diagram where, at each of its multiple points in the plane, exactly three strands are allowed to cross (pairwise transversely). Such triple-point diagrams have been studied in several …
Webinvariants obstruct the knot from being concordant to a knot of lower genus. For another 59 knots we show an explicit concordance, illustrated in the appendix. This extends the … 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.
