On the moments of Kloosterman sums and fibre products of Kloosterman curves

摘要

Let q = p~r with p = 3 and r ≥ 2. We give a recursion formula for the moments of a Kloosterman sum over the finite field F_q, which utilizes known weight formulae for the ternary Melas code M of length q - 1. The method is illustrated by giving explicit f
