Rational Symplectic Field Theory for Legendrian knots

Symplectic Geometry 2015-05-13 v3 Geometric Topology

Abstract

We construct a combinatorial invariant of Legendrian knots in standard contact three-space. This invariant, which encodes rational relative Symplectic Field Theory and extends contact homology, counts holomorphic disks with an arbitrary number of positive punctures. The construction uses ideas from string topology.
