Cyclotomic integers

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 WebOne of the most fundamental properties of cyclotomic elds in terms of basic algebraic number theory is that its ring of integers is rather easy to describe. Proposition 1. We have O Kn = Z[ ]; whereas computing the ring of integers for a number eld is very hard in general. Galois groups of cyclotomic elds are similarly easy to handle ...

WebAug 8, 2024 · A cyclotomic integer is prime if every time it divides a product it divides one of the factors. Because the norm of a product is the product of the norms, a factor of a cyclotomic integer has a norm that divides the norm of the given cyclotomic integer.
