Classification of Legendrian Circular Helix Links
نویسنده
چکیده
Lisa Traynor has described an example of a two-component Legendrian ‘circular helix link’ Λ0 ⊔ Λ1 in the 1-jet space of the circle (with its canonical contact structure) that is topologically but not Legendrian isotopic to the link Λ1 ⊔Λ0. We give a complete classification of the Legendrian realisations of this topological link type.

Legendrian Helix and Cable Links
Lisa Traynor has described an example of a two-component Legendrian ‘circular helix link’ Λ0 ⊔ Λ1 in the 1–jet space J(S) of the circle (with its canonical contact structure) that is topologically but not Legendrian isotopic to the link Λ1 ⊔ Λ0. We give a complete classification of the Legendrian realisations of this topological link type, as well as all other ‘cable links’ in J(S).
متن کاملClassification of Legendrian Knots and Links
The aim of this paper is to use computer program to generate and classify Legendrian knots and links. Modifying the algorithm in [11], we write a program in Java to generate all grid diagrams of up to size 10. Since classification of Legendrian links up to Legendrian isotopy is equivalent to grid diagrams modulo a set of Cromwell moves including translation, commutation and X:NE,X:SW (de)stabil...
متن کاملLegendrian Knots and Links Classified by Classical Invariants
It is shown that Legendrian (resp. transverse) cable links in S with its standard tight contact structure, i.e. links consisting of an unknot and a cable of that unknot, are classified by their oriented link type and the classical invariants (Thurston-Bennequin invariant and rotation number in the Legendrian case, self-linking number in the transverse case). The analogous result is proved for t...
متن کاملLegendrian Surgeries on Stabilized Legendrian Links
We use Seiberg-Witten monopoles and Ozsváth-Szabó invariants to distinguish between tight contact structures obtained by Legendrian surgeries on stabilized Legendrian links in tight contact 3-manifolds.
متن کاملPolynomial Invariants of Legendrian Links and Plane Fronts
We show that the framed versions of the Kauuman and HOMFLY poly-nomials of a Legendrian link in the standard contact 3-space and solid torus are genuine polynomials in the framing variable. This proves a series of conjectures of 5] and provides estimates for the Bennequin{Tabachnikov numbers of such links. In a series of recent papers 1{3], V. I. Arnold revived interest in the study of plane cu...
