On the rank of hypergeometric sheaves on higher dimensional tori

Antonio Rojas-León

We prove an explicit formula for the generic rank of hypergeometric perverse sheaves on higher dimensional tori over a finite field, as defined by Gabber and Loeser. This allows to…

An effective criterion for finite monodromy of $ℓ$ -adic sheaves

Antonio Rojas-León

We provide an effective version of Katz' criterion for finiteness of the monodromy group of a lisse, pure of weight zero, $ℓ$ -adic sheaf on a normal variety over a finite field,…
