Legendrian contact homology in $R^{3}$

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 $R^{3}$ . T…

Representations, sheaves, and Legendrian $(2, m)$ torus links

Baptiste Chantraine, Lenhard Ng, Steven Sivek

We study an $A_{\infty}$ category associated to Legendrian links in $R^{3}$ whose objects are $n$ -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 $N$ duality and Witten's connection between open Gromov-Witte…
