    Séminaire Math-Physique : Polynomiality of Hurwitz numbers

    Résumé : I will give an introduction to Hurwitz numbers, giving both a geometric and an algebraic definition, with several examples. I will give relations between Hurwitz numbers and Gromov-Witten theory and integrable hierarchies, some of them conjectural. These relations require or suggest certain polynomiality properties of Hurwitz numbers, and I will give some results in this vein.
    This is based on joint work with, in several configurations, G. Borot, M.A. Hahn, D. Lewanski, A. Popolitov, and S. Shadrin.
