WebOn explicit relations between cyclotomic numbers by Marc Conrad (Saarbrücken) 1. Introduction. For n ∈ N let εn be a primitive nth root of unity and D(n) the multiplicative group generated by the elements 1 − εkn with k 6 ≡ 0 mod n modulo roots of unity in order to avoid torsion. We call D(n) the group of cyclotomic numbers. 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 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.
