Ternary Kloosterman sums using Stickelberger's theorem and the Gross-Koblitz formula
arXiv:1006.1802
Abstract
We give results characterising ternary Kloosterman sums modulo 9 and 27. This leads to a complete characterisation of values that ternary Kloosterman sums assume modulo 18 and 54. The proofs uses Stickelberger's theorem, the Gross-Koblitz formula and Fourier analysis.
