Basic Results,In this chapter we prove some basic results on cyclotomic fields which will lay the groundwork for later chapters. We let ζ. denote a primitive .th root of unity. First we determine the ring of integers and discriminant of ?(ζ.). We start with the prime power case.

Dirichlet ,-series and Class Number Formulas,In this chapter we review some of the basic facts about .-series. Then their values at negative integers are given in terms of generalized Bernoulli numbers. Finally, we discuss the values at 1 and relations with class numbers.

,The Second Case of Fermat’s Last Theorem,by the class number. We now study the second case, namely.Again, the class number plays a role, but the units are also very important, which makes things much more difficult than in the first case. In fact, the second case is only known to hold for . < 125000, while the first case is known at present for . < 6 × 10..

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.
