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.

WebSep 14, 2024 · 1. 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.
