Title:	 Hurwitz spaces and divisors on moduli spaces of curves

Date:	Thu, Jan 24, 2013, 15:30 - 16:30

Place:	Lecture Hall

Abstract:	 Hurwitz spaces appeared in modern algebraic geometry in the
pivotal paper of Harris and Mumford on the Kodaira dimension of M_g.
Hurwitz spaces give rise to maps and correspondences between moduli
spaces of curves. In this talk we give examples of this and study the
induced maps on divisor classes on moduli spaces of curves. We
calculate some divisor classes and also discuss the Hodge bundle of
Hurwitz spaces. This is based on joint work with Alexis Kouvidakis.
