Equidistribution of Kloosterman sums over function fields (2406.10106v1)
Published 14 Jun 2024 in math.NT and math.AG
Abstract: We prove the Sato--Tate distribution of Kloosterman sums over function fields with explicit error terms, when the places vary in arithmetic progressions or short intervals. A joint Sato--Tate distribution of two ``different" exponential sums is also proved.
