    An Effective Criterion for Finite Monodromy of ℓ-Adic Sheaves 

    Rojas León, Antonio (Springer, 2023-02-01)
    We provide an effective version of Katz’ criterion for finiteness of the monodromy group of a lisse, pure of weight zero, -adic sheaf on a normal variety over a finite field, depending on the numerical complexity of the sheaf.
