Title:  What is ... the universal theta divisor?

Abstract: The Jacobian varieties of smooth projective curves fit 
together to form a family over the moduli space of curves called 
universal Jacobian, and the theta divisors of these curves form a 
divisor in the universal Jacobian.  I will explain how to construct 
extensions of the universal Jacobian and theta divisor over the moduli 
space of stable curves. The extensions depend on an extra stability 
parameter, and I will then study how the universal theta divisor varies 
with this parameter. This is a joint work with Jesse Kass.
