On Hurwitz Numbers and Hodge Integrals

  title={On Hurwitz Numbers and Hodge Integrals},
  author={Torsten Ekedahl and S. K. Lando and Michael Shapiro and Alek Vainshtein},
In this paper we find an explicit formula for the number of topologically different ramified coverings C → CP 1 (C is a compact Riemann surface of genus g) with only one complicated branching point in terms of Hodge integrals over the moduli space of genus g curves with marked points.
