,Stickelberger’s Theorem,p.hey will form the Stickelberger ideal. The proof involves factoring Gauss sums as products of prime ideals, and since Gauss sums generate principal ideals, we obtain relations in the ideal class group. As an application, we prove Herbrand’s theorem which relates the nontriviality of certain parts

Galois Groups Acting on Ideal Class Groups,o great advantage to reinterpret old results and to obtain new information on the structure of class groups. In this chapter we first give some results which are useful when working with class groups and class numbers. We then present the basic machinery, essentially Leopoldt’s Spiegelungssatz, whic

Measures and Distributions,As we shall see, many ideas from Chapters 4, 5, 7, and 8 fit into this general framework. The related concept of a measure yields a .-adic integration theory which allows us to interpret the .-adic .-function as a Mellin transform, as in the classical case.

,Iwasawa’s Theory of ℤ-extensions,motivation from the theory of curves over finite fields, which is known to have a strong analogy with the theory of number fields. In the case of curves, it is convenient to extend the field of constants to its algebraic closure, which amounts to adding on roots of unity. There is a natural generato
