Web1 de jan. de 2009 · We introduce a geometric invariant of knots in S 3, called the first-order genus, that is derived from certain 2-complexes called gropes, and we show it is computable for many examples.While computing this invariant, we draw some interesting conclusions about the structure of a general Seifert surface for some knots. 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.

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.
