For instance, all primes p 19 have h p = 1, so they are regular. Since h 23 = 3, 23 is regular. All primes less then 100 are regular except for 37, 59, and 67: h 37 = 37, h 59 = 359233, and h 67 = 6712739. It is ...

WebCYCLOTOMIC EXTENSIONS KEITH CONRAD 1. Introduction For a positive integer n, an nth root of unity in a eld is a solution to zn = 1, or equivalently is a root of Tn 1. There are at most ndi erent nth roots of unity in a eld since Tn 1 has at most nroots in a eld. A root of unity is an nth root of unity for some n.

In general the subgroup generated by the cyclotomic units is only of a finite index in the full group of units of O K ∗, where K = Q ( ζ + ζ − 1). Wikipedia says that the index is equal to the class number of K, which is good news here. I'm afraid that result is beyond me, but I would think WP is accurate here. births of 1965births of 1957In mathematics, a cyclotomic unit (or circular unit) is a unit of an algebraic number field which is the product of numbers of the form (ζ n − 1) for ζ n an n root of unity and 0 < a < n. births of 1950WebJan 17, 2002 · Title: Nontrivial Galois module structure of cyclotomic fields.
