The correspondence between augmentations and rulings for Legendrian knots

Symplectic Geometry 2016-09-07 v2 Geometric Topology

Abstract

We strengthen the link between holomorphic and generating-function invariants of Legendrian knots by establishing a formula relating the number of augmentations of a knot's contact homology to the complete ruling invariant of Chekanov and Pushkar.
