Title: Frobenius fields for Drinfeld modules of rank 2

Speaker: Alina Cojocaru, Princeton & MSRI

Abstract:
We will discuss two techniques of obtaining upper bounds for the number pf primes P for which the field generated by the Frobenius at P of a Drinfeld module of rank 2, in generic characteristic, is equal to a fixed imaginary quadratic function field. This is joint work with Chantal David (Concordia Univ., Montreal).
