Abstract:  This is joint work with T. Ekedahl, S. Lando and A. Vainshtein. We found an explicit formula for the number of topologically different ramified coverings from  C to CP1, where  C is a compact Riemann surface of genus gwith only one complicated ramification point in terms of Hodge integrals over the moduli space of genus g curves with marked points.
