Local convolution of-adic sheaves on the torus

A Rojas-León - Mathematische Zeitschrift, 2013 - Springer
For K and L two ℓ-adic perverse sheaves on the one-dimensional torus G _ m, ̄ k over the
algebraic closure of a finite field, we show that the local monodromies of their convolution K …

On the number of elements with prescribed norm and trace

R Alvarenga, H Borges - arXiv preprint arXiv:2308.15595, 2023 - arxiv.org
Let F_q be the finite field with cardinality q, where q is a prime power. Given a finite field
extension F_q^ n over F_q and a, b in (F_q)^{*}, we investigate in this article the number …

TENSOR AND CONVOLUTION DIRECT IMAGE OF ℓ‐ADIC SHEAVES

A Rojas‐León - Mathematika, 2020 - Wiley Online Library
Given a Galois étale map of varieties π: Y→ X and an ℓ‐adic sheaf or complex on Y, we
study two cohomological operations: the tensor direct image and the convolution direct …

We improve the bounds for the number of rational points of an Artin-Schreier covering of a
curve defined over a finite field, following ideas of Rojas Leon and Wan. This number of …
