# CFT and topological recursion

@article{Kostov2010CFTAT, title={CFT and topological recursion}, author={Ivan Kostov and Nicolas Orantin}, journal={Journal of High Energy Physics}, year={2010}, volume={2010}, pages={1-30} }

We study the quasiclassical expansion associated with a complex curve. In a more specific context this is the 1/N expansion in U(N)-invariant matrix integrals. We compare two approaches, the CFT approach and the topological recursion, and show their equivalence. The CFT approach reformulates the problem in terms of a conformal field theory on a Riemann surface, while the topological recursion is based on a recurrence equation for the observables representing symplectic invariants on the complex…
