WebPRESENCE OF A FOURTH ROOT OF UNITY J. MINA´Cˇ ∗ AND Z. REICHSTEIN ∗ Abstract. We study quadratic forms that can occur as trace forms qL/K of Galois field extensions L/K, under the assumption that K con-tains a primitive 4th root of unity. M. Epkenhans conjectured that qL/K is always a scaled Pfister form. We prove this conjecture and ... WebFirst of all, if m and n are relatively prime, then the primitive (mn)th roots of unity are products of the primitive mth roots of unity and the primitive nth roots of unity. Thus, we …

WebFollowing the above procedure, we first find a primtive 5th root of unity. We might find the 5th primitive root: α = − 1 − 5 4 − i 5 − 5 8. We next take a 5th root of α to obtain a … WebFor example, i is an 8th root of unity (for i 8 = 1), but not a primitive 8th root of unity; i is a primitive 4th root of unity. Now for any integer 1 ≤ k < n, α 1 k is a generator of G iff gcd(k,n) = 1, see Lemma 7.3.10. If n = 8 we have, α 1 1, α 1 3, α 1 5 and α 1 7 are generators of this cyclic group.
