The distribution of primes and an introduction to class field theory,urn out to be distributed uniformly (in some sense) among the members of the group; in particular each group element is the image of infinitely many primes. Except in certain special cases, however, the proof of this depends upon facts from class field theory which will not be proved in this book. T

The distribution of ideals in a number ring,We are going to exploit the geometric methods of chapter 5 to establish results about the distribution of the ideals of a number ring R. In a sense to be made precise shortly, we will show that the ideals are approximately equally distributed among the ideal classes, and the number of ideals with ‖I‖ ≤ t, t ≥ 0, is approximately proportional to t.

Number fields and number rings, some algebraic number α ∈ ℂ. If α is a root of an irreducible polynomial over ℚ, having degree n, then . and representation in this form is unique; in other words, {1.,α.} is a basis for ℚ[α] as a vector space over ℚ.

The ideal class group and the unit group,tiplication defined in the obvious way, and the fact that this is actually a group was proved in chapter 3 (Corollary 1 of Theorem 15). In this chapter we will prove that the ideal class group of a number ring is finite and establish some quantitative results that will enable us to determine the ideal class group in specific cases.
