  "abstract": "We study the passage from Drinfeld-A'-modules to Drinfeld-A-modules for a given finite flat inclusion A \\subset A'. We show that this defines a morphism from the moduli space of Drinfeld-A'-modules to the moduli space of Drinfeld-A-modules which is proper but in general not representable. For Drinfeld-Anderson shtuka and abelian sheaves instead of Drinfeld modules we obtain the same results.",
