Generic Monodromy of Drinfeld Modular Varieties in Special Characteristic
Florian Breuer (University of Newcastle)
Abstract:
By combining theorems of Drinfeld and Strauch, we show that the monodromy representation on the special fiber of a Drinfeld modular variety, with level not divisible by the characteristic, is surjective.
We illustrate this result in the special case of Drinfeld
-modules in level
, and apply this to show that the Kronecker factors of a Drinfeld modular polynomial in rank r are irreducible.
This is joint work with Gebhard Böckle.
