Grid Diagrams, Braids, and Contact Geometry

Lenhard Ng, Dylan Thurston

We use grid diagrams to present a unified picture of braids, Legendrian knots, and transverse knots.

Rational Symplectic Field Theory for Legendrian knots

Lenhard Ng

We construct a combinatorial invariant of Legendrian knots in standard contact three-space. This invariant, which encodes rational relative Symplectic Field Theory and extends cont…

A family of transversely nonsimple knots

Tirasan Khandhawit, Lenhard Ng

We apply knot Floer homology to exhibit an infinite family of transversely nonsimple prime knots starting with . We also discuss the combinatorial relationship between gr…
