      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.

      Finite monodromy of some families of exponential sums 

      Rojas León, Antonio (Elsevier, 2019-04)
      Given a prime p and an integer d > 1, we give a numerical criterion to decide whether the ℓ-adic sheaf associated to the ...
