Abstract: We show that flow tree degenerations of holomorphic curves give rise to skein lifts for multiple covers of a 3-manifold branched along a link. This leads to wall-crossing formulas and a new formula for the HOMFLYPT polynomial from a braid presentation of a knot. The talk reports on joint work with Longhi, Park, and Shende.
This is a talk in our Geometry and Topology Seminar Series.
