The Galois ring $\GR$ of characteristic $p^n$ having $p^{mn}$ elements is a finite extension of the ring of integers modulo $p^n$, where $p$ is a prime number and $n,m$ are positive integers. In this paper, we develop the concepts of Jacobi sums over $\GR$ and under the assumption that the generating additive character of $\GR$ is trivial on maximal ideal of $\GR$, we obtain the basic relationship between Gauss sums and Jacobi sums, which allows us to determine the absolute value of the Jacobi sums.
Abstract
The Galois ring $\GR$ of characteristic $p^n$ having $p^{mn}$ elements is a finite extension of the ring of integers modulo $p^n$, where $p$ is a prime number and $n,m$ are positive integers. In this paper, we develop the concepts of Jacobi sums over $\GR$ and under the assumption that the generating additive character of $\GR$ is trivial on maximal ideal of $\GR$, we obtain the basic relationship between Gauss sums and Jacobi sums, which allows us to determine the absolute value of the Jacobi sums.
