The Galois representations associated to a Drinfeld module in special characteristic—II: Openness Original Research Article

Let φ be a Drinfeld A-module in special characteristic image over a finitely generated field K. For any finite set P of primes image of A let ΓP denote the image of Gal(Ksep/K) in its representation on the product of the image-adic Tate modules of φ for all image. We determine ΓP up to commensurability.
