Title: Generalized double Hurwitz numbers, topological recursion, and ELSV-type formulas<\/p>\n\n\n\n
Abstract: In the talk, I’ll briefly recall the origin and the main properties of spectral curve topological recursion, and then I will describe in more detail our results on explicit closed algebraic formulas for generating functions of generalized double Hurwitz numbers, and how this allows proving topological recursion for a wide class of problems. After that I’ll talk about the implications for the so-called ELSV-type formulas (relating Hurwitz-type numbers to intersection numbers on the moduli spaces of algebraic curves); in particular, I’ll explain how this almost immediately gives proofs (of a purely combinatorial-algebraic nature) of the original ELSV formula and of its r-spin generalization (originally conjectured by D.Zvonkine).<\/p>\n\n\n\n
The talk is based on a series of joint works with B.Bychkov, M.Kazarian, and S.Shadrin, arXiv:2008.13123, 2012.14723, 2106.08368, 2206.14792. <\/p>\n\n\n\n
This talk can be thought of as a continuation of Boris Bychkov’s talk on November, 23.<\/p>\n\n\n\n
