On the structure of the Galois group of the maximal pro-$p$ extension with restricted ramification over the cyclotomic $\mathbb{Z}_p$-extension

open access: yes, 2018
Let $k_\infty$ be the cyclotomic $\mathbb{Z}_p$-extension of an algebraic number field $k$. We denote by $S$ a finite set of prime numbers which does not contain $p$, and $S(k_\infty)$ the set of primes of $k_\infty$ lying above $S$. In the present paper,

On some determinants involving cyclotomic units

open access: yes, 2019
For each odd prime $p$, let $ _p$ denote a primitive $p$-th root of unity. In this paper, we study the determinants of some matrices with cyclotomic unit entries. For instance, we show that when $p\equiv 3\pmod4$ and $p>3$ the determinant of the matrix $\(\frac{1- _p^{j^2k^2}}{1- _p^{j^2}}\)_{1\le j,k\le (p-1)/2}$ can be written as $(-1)^{\frac{h(

On the Orthogonal of Cyclotomic Units in Positive Characteristic

open access: yesJournal of Number Theory, 1999
This is a very interesting and powerful piece of mathematics. Let \(A:= \mathbb{F}_q[T]\) where \(\mathbb{F}_q\) is the finite field of \(q=p^m\) elements. Let \(P\in A\) be a monic prime of degree \(d\). In work by the author [J. Number Theory 78, 228-252 (1999; Zbl 0937.11020)] and \textit{F. Schultheis} [J.

On a cyclotomic unit and related products

open access: yesJournal of Number Theory, 1991
AbstractLet p be an odd prime, ζ a primitive pth root of unity. It is proved that Π(1 + iζk)k, 1 ≤ k ≤ p − 1 is a perfect pth power in Z(iζ) only if p divides Σtp − 3, 1 ≤ t ≤ ⌊p4⌋, and that it is a perfect pth power for P = 241. Properties of the general product Π(1 + aqk)k, 1 ≤ k ≤ n, are investigated.
