We give a geometric interpretation of the coefficients of the HOMFLYPT polynomial of any link in the three-sphere as counts of holomorphic curves. The curves counted live in the resolved conifold where they have boundary on a shifted copy of the link conormal, as predicted by Ooguri and Vafa.. To prove this, we introduce a new method to define invariant counts of holomorphic curves with Lagrangian boundary: we show geometrically that the wall crossing associated to boundary bubbling is the framed skein relation. It then follows that counting holomorphic curves by the class of their boundary in the skein of the Lagrangian brane gives a deformation invariant curve count. This is a mathematically rigorous incarnation of the fact that boundaries of open topological strings create line defects in Chern-Simons theory, as described by Witten. The technical key to skein invariance is a new compactness result: if the Gromov limit of J-holomorphic immersions collapses a curve component, then its image has a singularity worse than a node.
The Thurston-Bennequin invariant provides one notion of self-linking for any homologically-trivial Legendrian curve in a contact three-manifold. Here we discuss related analytic notions of self-linking for Legendrian knots in Euclidean space. Our def
We determine the skein-valued Gromov-Witten partition function for a single toric Lagrangian brane in $mathbb{C}^3$ or the resolved conifold. We first show geometrically they must satisfy a certain skein-theoretic recursion, and then solve this equat
We analyze two different fibrations of a link complement M constructed by McMullen-Taubes, and studied further by Vidussi. These examples lead to inequivalent symplectic forms on a 4-manifold X = S x M, which can be distinguished by the dimension of
We show that the exterior derivative operator on a symplectic manifold has a natural decomposition into two linear differential operators, analogous to the Dolbeault operators in complex geometry. These operators map primitive forms into primitive fo
We introduce filtered cohomologies of differential forms on symplectic manifolds. They generalize and include the cohomologies discussed in Paper I and II as a subset. The filtered cohomologies are finite-dimensional and can be associated with differ
