在第6章中,我们介绍了二次高斯和的概念。在这一章中,将介绍高斯和的一个更一般的概念。这些和有许多应用。在第9章中,我们将把它们作为证明三次和四次互反定律的工具。这里我们将考虑有限域中系数方程解的个数的计数问题。在这方面,雅可比和的概念以自然的方式出现。雅可比和本身就很有趣,我们将研究它们的一些性质。
In Chapter 6 we introduced the notion of a quadratic Gauss sum. In this chapter a more general notion of Gauss sum will be introduced. These sums have many applications. They will be used in Chapter 9 as a tool in the proofs of the laws of cubic and biquadratic reciprocity. Here we shall consider the problem of counting the number of solutions of equations with coefficients in a finite field. In this connection, the notion of a Jacobi sum arises in a natural way. Jacobi sums are interesting in their own right, and we shall develop some of their properties.
