Small genus knots in lens spaces have small bridge number
In a lens space X of order r a knot K representing an element of the fundamental group π1X ∼= Z/rZ of order s ≤ r contains a connected orientable surface S properly embedded in its exterior X − N(K) such that ∂S intersects the meridian of K minimally s times. Assume S has just one boundary component. Let g be the minimal genus of such surfaces for K , and assume s ≥ 4g − 1. Then with respect to...
متن کاملGenus one 1-bridge knots and Dunwoody manifolds
In this paper we show that all 3-manifolds of a family introduced by M. J. Dunwoody are cyclic coverings of lens spaces (eventually S), branched over genus one 1-bridge knots. As a consequence, we give a positive answer to the Dunwoody conjecture that all the elements of a wide subclass are cyclic coverings of S branched over a knot. Moreover, we show that all branched cyclic coverings of a 2-b...
متن کاملKNOTS OF GENUS ONE Or on the number of alternating knots of given genus
We prove that any non-hyperbolic genus one knot except the trefoil does not have a minimal canonical Seifert surface and that there are only polynomially many in the crossing number positive knots of given genus or given unknotting number.
متن کاملKnots of Genus Two
We classify all knot diagrams of genus two and three, and give applications to positive, alternating and homogeneous knots, including a classification of achiral genus 2 alternating knots, slice or achiral 2-almost positive knots, a proof of the 3and 4-move conjectures, and the calculation of the maximal hyperbolic volume for weak genus two knots. We also study the values of the link polynomial...
متن کاملUnknotting Genus One Knots
There is no known algorithm for determining whether a knot has unknotting number one, practical or otherwise. Indeed, there are many explicit knots (11328 for example) that are conjectured to have unknotting number two, but for which no proof of this fact is currently available. For many years, the knot 810 was in this class, but a celebrated application of Heegaard Floer homology by Ozsváth an...
