Speaker: Sumita Garai, Penn State

Abstract: For a generic, rank $r$ Drinfeld module, we discuss its reductions and their endomorphism rings. We discuss the significance of the Frobenius indices and prove that they can be arbitrarily large. We also give an algorithm to compute these indices explicitly and a basis for the endomorphism ring. This is a joint work with Mihran Papikian.
