Cyclotomic number
WebCyclotomic Fields Let ω = e 2 π i / m. Then every conjugate of ω must be of the form ω k for some 1 ≤ k ≤ m coprime to m (since every conjugate must also be a m root of unity, and not an n th root for any n < m. The converse is also true: Theorem: The conjugates of ω are ω k for 1 ≤ k ≤ m coprime to m. WebMar 24, 2024 · TOPICS.

WebThen On has odd class number by [Was82, Theorem 10.4(b)] and so Rn+ = On [1/2] has odd class number. Every totally positive unit in On is a square by Weber’s Theorem [Web99] and there is one prime p in Fn above 2. In number theory, a cyclotomic field is a number field obtained by adjoining a complex root of unity to Q, the field of rational numbers. Cyclotomic fields played a crucial role in the development of modern algebra and number theory because of their relation with Fermat's Last Theorem.

WebJan 1, 2013 · It is known that cyclotomic numbers can be determined from the knowledge of Gauss sums. How- ever, explicit evaluation of Gauss sums of large orders is difficult in general [1, pp. 98–99 and p. 152], so one cannot expect a general formula for cyclotomic numbers for large e.
