Knot invariants and topological strings Original Research Article

We find further evidence for the conjecture relating large N Chern–Simons theory on S3 with topological string on the resolved conifold geometry by showing that the Wilson loop observable of a simple knot on S3 (for any representation) agrees to all orders in N with the corresponding quantity on the topological string side. For a general knot, we find a reformulation of the knot invariant in terms of new integral invariants, which capture the spectrum (and spin) of M2 branes ending on M5 branes embedded in the resolved conifold geometry. We also find an intriguing link between knot invariants and superpotential terms generated by worldsheet instantons in N=1 supersymmetric theories in 4 dimensions.
