Title: Skeins on branes
Abstract: We give an enumerative interpretation of coefficients of the HOMFLY polynomial of a knot in the 3-sphere as a count of holomorphic curves with boundary on a version of the Lagrangian conormal of the knot in the resolved conifold. A key ingredient in the proof is the definition of counts of holomorphic curves with boundary in the skein module of the Lagrangian brane where they have their boundary. The talk reports on joint work with Vivek Shende.
