Enumerating number fields [PDF]

open access: yesAnnals of Mathematics, 2020
We construct small models of number fields and deduce a better bound for the number of number fields of given degree and bounded discriminant.

Short Principal Ideal Problem in multicubic fields

open access: yesJournal of Mathematical Cryptology, 2020
One family of candidates to build a post-quantum cryptosystem upon relies on euclidean lattices. In order to make such cryptosystems more efficient, one can consider special lattices with an additional algebraic structure such as ideal lattices.

Some Remarks on the Divisibility of the Class Numbers of Imaginary Quadratic Fields

open access: yesMathematics, 2022
For a given integer n, we provide some families of imaginary quadratic number fields of the form Q(4q2−pn), whose ideal class group has a subgroup isomorphic to Z/nZ.

Semicircular elements induced by p-adic number fields [PDF]

open access: yesOpuscula Mathematica, 2017
In this paper, we study semicircular-like elements, and semicircular elements induced by \(p\)-adic analysis, for each prime \(p\). Starting from a \(p\)-adic number field \(\mathbb{Q}_{p}\), we construct a Banach \(*\)-algebra \(\mathfrak{LS}_{p}\), for

Ramification in quartic cyclic number fields $K$ generated by $x^4+px^2+p$ [PDF]

open access: yesMathematica Bohemica, 2021
If $K$ is the splitting field of the polynomial $f(x)=x^4+px^2+p$ and $p$ is a rational prime of the form $4+n^2$, we give appropriate generators of $K$ to obtain the explicit factorization of the ideal $q{\mathcal O}_K$, where $q$ is a positive rational

Number Fields [PDF]

open access: yes, 2023
Number Fields is a textbook for algebraic number theory. It grew out of lecture notes of master courses taught by the author at Radboud University, the Netherlands, over a period of more than four decades. It is self-contained in the sense that it uses only mathematics of a bachelor level, including some Galois theory.

A generalization of arithmetic derivative to p-adic fields and number fields [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
The arithmetic derivative is a function from the natural numbers to itself that sends all prime numbers to 1 and satisfies the Leibniz rule. The arithmetic partial derivative with respect to a prime p is the p-th component of the arithmetic derivative ...

On dynamical systems induced by p-adic number fields [PDF]

open access: yesOpuscula Mathematica, 2015
In this paper, we construct dynamical systems induced by \(p\)-adic number fields \(\mathbb{Q}_{p}\). We study the corresponding crossed product operator algebras induced by such dynamical systems.

Norms in finite galois extensions of the rationals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
We show that under certain conditions a rational number is a norm in a given finite Galois extension of the rationals if and only if this number is a local norm at a certain finite number of places in a certain finite abelian extension of the rationals.
