EXPLICIT KUMMER GENERATORS FOR CYCLOTOMIC EXTENSIONS [PDF]

open access: yesJP Journal of Algebra, Number Theory and Applications, 2022
Summary: If \(p\) is a prime number congruent to 1 modulo 3, then we explicitly describe an element of the cyclotomic field \(\mathbb Q(\zeta_3)\) whose third root generates the cubic subextension of \(\mathbb Q(\zeta_{3p})/\mathbb Q(\zeta_3)\). Similarly, if \(p\) is a prime number congruent to 1 modulo 4, then we explicitly describe an element of the

A note on quadratic cyclotomic extensions

open access: yes, 2022
This paper provides two characterizations of the primitive roots of unity in quadratic cyclotomic extensions over arbitrary fields. Firstly, we introduce a mapping from $\mathbb{N}$ to $\mathbb{N}$ crucial for describing these roots, closely tied to their order over the field.

Fitting ideals of class groups in Carlitz–Hayes cyclotomic extensions [PDF]

open access: yesJournal of Number Theory, 2022
We generalize some results of Greither and Popescu to a geometric Galois cover $X\rightarrow Y$ which appears naturally for example in extensions generated by $\mathfrak{p}^n$-torsion points of a rank 1 normalized Drinfeld module (i.e. in subextensions of Carlitz-Hayes cyclotomic extensions of global fields of positive characteristic).

On Nilpotent Extensions of ∞-Categories and the Cyclotomic Trace

open access: yesInternational Mathematics Research Notices, 2021
AbstractWe do three things in this paper: (1) study the analog of localization sequences (in the sense of algebraic $K$-theory of stable $\infty $-categories) for additive $\infty $-categories, (2) define the notion of nilpotent extensions for suitable $\infty $-categories and furnish interesting examples such as categorical square-zero extensions, and

A Result of Bass on Cyclotomic Extension Fields [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
In [1] Bass stated the result given below as Proposition 1 and derived some consequences. His proof of the proposition itself, however, contains a gap; Lemmas 2 and 3 are false as stated. The purpose of this note is to fill the gap by proving the slightly stronger Proposition 2. We retain the notation of [1]. In particular k,,=k(Dm) where A;m = e2rilm.

Radical and cyclotomic extensions of the rational numbers [PDF]

open access: yesProceedings of the American Mathematical Society, 2007
The principal result in this article is the proof that the Galois closure \(E/\mathbb{Q}\) of a radical extension of the rational numbers \(\mathbb{Q}\) (i.e. an extension \(R = \mathbb{Q}[\alpha]\), where \(\alpha^n \in \mathbb{Q}\) for some positive integer \(n\)) contains a (maximal) cyclotomic extension \(K\) of \(\mathbb{Q}\) whose index in \(E ...
