Legendrian Conormals of 2-Knots
نویسندگان
چکیده
LetK be a 2-knot. The conormal Lift ΛK ofK is a Legendrian submanifold in the unit cotangent bundle U∗R4. One can use Legendrian homology on ΛK to define an invariant of K which is a differential graded algebra partly generated by the Reeb chords of ΛK . We try to count and specify these Reeb chords by describing the conormal lifts, of 2-knots given as closed 2dimensional braids, as 1-jet graphs of ΛS2 and get a description for some of these chords.

Cabling and Transverse Simplicity
We study Legendrian knots in a cabled knot type. Specifically, given a topological knot type K, we analyze the Legendrian knots in knot types obtained from K by cabling, in terms of Legendrian knots in the knot type K. As a corollary of this analysis, we show that the (2, 3)-cable of the (2, 3)-torus knot is not transversely simple and moreover classify the transverse knots in this knot type. T...
متن کاملThe Legendrian Satellite Construction
The spaces R3 and S1 ×R2 both have a standard contact structure given by the kernel of the 1form dz−y dx, where we view the solid torus S1×R2 as R3 modulo the relation (x, y, z) ∼ (x+1, y, z). We will assume that the reader is familiar with some basic concepts in Legendrian knot theory, such as front projections, the Thurston-Bennequin number, and the rotation number; see, e.g., [8], which we w...
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 کاملTopologically Trivial Legendrian Knots
This paper deals with topologically trivial Legendrian knots in tight and overtwisted contact 3-manifolds. The first parts (Sections 1-3) contain a thorough exposition of the proof of the classification of topologically trivial Legendrian knots (i.e. Legendrian knots bounding embedded 2-disks) in tight contact 3-manifolds (Theorem 1.7), and, in particular, in the standard contact S. These parts...
متن کاملKnots and Contact Geometry Ii: Connected Sums
We study the behavior of Legendrian and transverse knots under the operation of connected sums. As a consequence we show that there exist Legendrian knots that are not distinguished by any known invariant. Moreover, we classify Legendrian knots in some non-Legendrian simple knot types.
