Masser-Wüstholz bound for reducibility of Galois representations for Drinfeld modules of arbitrary rank (2303.12399v3)

Abstract: In this paper, we give an explicit bound on the irreducibility of mod-$\mathfrak{l}$ Galois representation for Drinfeld modules of arbitrary rank without complex multiplication. This is a function field analogue of Masser-W\"ustholz bound on irreducibility of mod-$\ell$ Galois representation for elliptic curves over number field.
