Open Hurwitz numbers and the mKP hierarchy - Alexandr Buryak, HSE (2026-02-27)Abstract: We give a natural definition of open Hurwitz numbers, where the weight of each ramified covering includes an integer parameter N taken to the power that is equal to the number of boundary components of a Riemann surface with boundary mapping to the complex projective line. We prove that the resulting sequenc...
