Torsion in linearized contact homology for Legendrian knots
Robert Lipshitz, Lenhard Ng
We present examples of Legendrian knots in that have linearized Legendrian contact homology over containing torsion. As a consequence, we show that ther…
Braid Loops with infinite monodromy on the Legendrian contact DGA
Roger Casals, Lenhard Ng
We present the first examples of elements in the fundamental group of the space of Legendrian links in the standard contact 3-sphere whose action on the Legendrian contact DGA is o…
Legendrian contact homology in
John B. Etnyre, Lenhard L. Ng
This is an introduction to Legendrian contact homology and the Chekanov-Eliashberg differential graded algebra, with a focus on the setting of Legendrian knots in . T…
Representations, sheaves, and Legendrian torus links
Baptiste Chantraine, Lenhard Ng, Steven Sivek
We study an category associated to Legendrian links in whose objects are -dimensional representations of the Chekanov-Eliashberg differential graded al…
Higher genus knot contact homology and recursion for colored HOMFLY-PT polynomials
Tobias Ekholm, Lenhard Ng
We sketch a construction of Legendrian Symplectic Field Theory (SFT) for conormal tori of knots and links. Using large duality and Witten's connection between open Gromov-Witte…
A complete knot invariant from contact homology
Tobias Ekholm, Lenhard Ng, Vivek Shende
We construct an enhanced version of knot contact homology, and show that we can deduce from it the group ring of the knot group together with the peripheral subgroup. In particular…
