Title:  Shimura varieties over the integers

Abstract:  Shimura varieties are quotients of hermitian symmetric domains by arithmetic groups. They generalize the classical elliptic modular curves, are defined over number fields and play a central role in number theory and the Langlands program. I will discuss some classical work and more recent progress on the problem of describing the structure of some of these varieties over the integers and, in particular, their reductions modulo primes.
