On Kloosterman sums over finite fields of characteristic 3 (1601.07039v1)
Published 23 Jan 2016 in math.NT and math.CO
Abstract: We study the divisibility by 3k of Kloosterman sums K(a) over finite fields of characteristic 3. We give a new recurrent algorithm for finding the largest k, such that 3k divides the Kloosterman sum K(a). This gives a new simple test for zeros of such Kloosterman sums.
