Cyclotomic polynomials over cyclotomic fields

Sung Doo Kim and June Bok Lee

Yonsei University, Yonsei University

Abstract

In this paper, we find the minimal polynomial of a primitive root of unity over cyclotomic fields. From this, we factorize cyclotomic polynomials over cyclotomic fields and investigate the coefficients of $\Phi_{3n}(x)$ when $3 \nmid n$.

Keywords: factorization, cyclotomic polynomial, cyclotomic field

MSC numbers: Primary 12D05
