http://virtualmath1.stanford.edu/~conrad/121Page/handouts/cyclotomic.pdf WebBy a cyclotomic field, we shall mean a subfield of the complex numbers C generated over the rational numbers Q by a root of unity. Let k be an imaginary cyclotomic field. Let Cn = e2ri/" for any integer n > 1. There is then a unique integer m > 2, m t 2 mod 4, such that k Q(Qm); we call m the conductor of k. We consider in this paper two objects associated …

WebOct 4, 2024 · $\begingroup$ Well, if you want the heavy hammer, it’s because the Galois group is abelian, and so by the Kronecker-Weber Theorem the extension is contained in a cyclotomic extension. But presumably, you don’t know this yet. So this leads to the request: please provide context!Tell us what you do know, or where this question came about, so … WebMay 28, 2024 · 1 Let F = Q ( ξ p) be the p t h cyclotomic field. What is the norm of N ( 1 + ξ p)? I’ve figured out that N ( 1 − ξ p) = p, as this can easily be seen from the minimal polynomial of ξ p. I’m stuck on how to find N ( 1 + ξ p), though. field-theory algebraic-number-theory roots-of-unity Share Cite Follow asked May 28, 2024 at 16:38 the man formal flowy white jumpsuit
On the RLWE/PLWE equivalence for cyclotomic number fields
WebNov 20, 2024 · Let p be an integer and let H (p) be the class-number of the field. where ζp is a primitive p -th root of unity and Q is the field of rational numbers. It has been proved … WebApr 28, 2024 · We focus on the study of cyclotomic number fields for obvious reasons. We also recall what is understood by equivalence, and how it relates to the condition number. In Sect. 3 we start by recalling the equivalence in the power of two cyclotomic case (proof included for the convenience of the reader) and for the family studied in [ 15 ]. WebJan 1, 2014 · The number field K_ {m} = \mathbb {Q} (\zeta _ {m}) is called the mth cyclotomic field. In this chapter we develop the most basic facts about cyclotomic fields, focusing mainly on the case m = p, an odd prime number.
