WebLemma 0.2. For any prime power pr and the associated cyclotomic eld K= Q( pr), N K=Q(1 pr) = p. The order of subtraction within the norm is designed to make the right side involve no sign, regardless of whether or not p= 2. Note also that this lemma applies even when pr = 2, in which case K= Q and 1 pr = 1 ( 1) = 2. Proof. Let f= pr 2Z[X], so f ...

WebTo describe cyclotomic extensions, we need to use the Euler phi function. If n is a positive integer, let ¢(n) be the number of integers between 1 and n that are relatively prime to n. The problems below give the main properties of the Euler phi function. We also need to know about the group of units crypto lock
