Streszczenie
We give an explicit bound on the irreducibility of the mod-$\mathfrak l$ Galois representation for Drinfeld modules of arbitrary rank without complex multiplication. This is a function field analogue of the Masser–Wüstholz bound on irreducibility of the mod-$\ell $ Galois representation for elliptic curves over a number field.
