A CLASSIFICATION OF EXTENSIONS GENERATED BY A ROOT OF AN EISENSTEIN-DUMAS POLYNOMIAL [PDF]

open access: yesJournal of Algebraic Systems
It is known that for a discrete valuation v of a field K with value group Z, an valued extension field (K′, v′) of (K, v) is generated by a root of an Eisenstein polynomial with respect to v having coefficients in K if and only if the extension (K′, v′)/(

Topological entropy for locally linearly compact vector spaces and field extensions

open access: yesTopological Algebra and its Applications, 2020
Let 𝕂 be a discrete field and (V, ϕ) a pair consisting of a locally linearly compact 𝕂-space V and a continuous endomorphism ϕ: V → V. We provide the formulae to compute the topological entropy ent* of the flow (V, ϕ) subject to either extension or ...

Infinite Towers of Galois Defect Extensions of Kaplansky Fields

open access: yesAnnales Mathematicae Silesianae, 2018
We give conditions for Kaplansky fields to admit infinite towers of Galois defect extensions of prime degree. As proofs of the presented facts are constructive, this provides examples of constructions of infinite towers of Galois defect extensions of ...

Global Solvably Closed Anabelian Geometry

open access: yes, 2006
In this paper, we study the pro-Σ anabelian geometry of hyperbolic curves, where Σ is a nonempty set of prime numbers, over Galois groups of “solvably closed extensions” of number fields — i.e., infinite extensions of number fields which have ...

PROJECTIVE EXTENSIONS OF FIELDS

open access: yesJournal of the London Mathematical Society, 2006
A field K admits proper projective extensions, i.e. Galois extensions where the Galois group is a nontrivial projective group, unless K is separably closed or K is a pythagorean formally real field without cyclic extensions of odd degree. As a consequence, it turns out that almost all absolute Galois groups decompose as proper semidirect products.

ISA Extensions for Finite Field Arithmetic - Accelerating Kyber and NewHope on RISC-V

open access: yesIACR Cryptology ePrint Archive, 2020
We present and evaluate a custom extension to the RISC-V instruction set for finite field arithmetic. The result serves as a very compact approach to software-hardware co-design of PQC implementations in the context of small embedded processors such as ...

Reverse Mathematics and Algebraic Field Extensions [PDF]

open access: yesDe Computis, 2012
This paper analyzes theorems about algebraic field extensions using the techniques of reverse mathematics. In section §2, we show that WKL0 is equivalent to the ability to extend F-automorphisms of field extensions to automorphisms of $\bar F$ , the ...

The product of a quartic and a sextic number cannot be octic

open access: yesOpen Mathematics
In this article, we prove that the product of two algebraic numbers of degrees 4 and 6 over Q{\mathbb{Q}} cannot be of degree 8. This completes the classification of so-called product-feasible triplets (a,b,c)∈N3\left(a,b,c)\in {{\mathbb{N}}}^{3} with a ...

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...

I will see it done: Metonymic extensions of the verb see in English

open access: yesCrossroads, 2021
English verbs of perception appear to be significant generators of divergent polysemous senses. The aim of this paper is to propose a dictionary study of the verb see.
