Knots, links and branes at large $$N$$. (English) Zbl 0990.81545
Summary: We consider Wilson loop observables for Chern-Simons theory at large $$N$$ and its topological string dual and extend the previous checks for this duality to the case of links. We find an interesting structure involving representation/spin degeneracy of branes ending on branes which features in the large $$N$$ dual description of Chern-Simons theory. This leads to a refinement of the integer invariants for links and knots. We illustrate our results with explicit computations on the Chern-Simons side.
