Title: Orbifold Hurwitz Numbers and Topological Recursion

Abstract: How many ways are there to map a genus g Riemann surface
to the Riemann sphere? We obtain Hurwitz numbers by counting such
maps with prescribed branching conditions. In recent work with
Oliver Leigh and Paul Norbury, we show that a certain class of
Hurwitz numbers is generated by topological recursion. The talk
in matrix models, enumeration of surface tilings, intersection theory
on moduli spaces, enumerative geometry of threefolds, statistical
mechanical models, quantum invariants of knots, topological string
theory, and probably a lot more!
