Kloosterman sums over finite Frobenius rings (1910.00165v1)
Published 1 Oct 2019 in math.NT and math.RA
Abstract: We study Kloosterman sums in a generalized ring-theoretic context, that of finite commutative Frobenius rings. We prove a number of identities for twisted Kloosterman sums, loosely clustered around moment computations.
