Matrix Kloosterman sums modulo prime powers

Márton Erdélyi, Árpád Tóth, Gergely Zábrádi

We give optimal bounds for matrix Kloosterman sums modulo prime powers extending earlier work of the first two authors on the case of prime moduli. These exponential sums arise in…

The distribution and density of cyclic groups of the reductions of an elliptic curve over a function field

Márton Erdélyi

Let $K$ be a global field of finite characteristic $p \geq 2$ , and let $E / K$ be a non-isotrivial elliptic curve. We give an asympotoic formula of the number of places $ν$ for which t…
