Geometria Maroni Divisors on Hurwitz Spaces Alexis Kouvidakis 16-06-2016 - 15:45 AULA 211 (Largo San L. Murialdo,1)
The moduli spaces H_{d,g} of covers of genus g and degree d of the projective line are known as Hurwitz spaces. We will discuss the Maroni stratification on such Hurwitz spaces. This stratification has a stratum that is a divisor only if d − 1 divides g and we will approximate the class of this divisor in the compactified Hurwitz space. |
