Bounds for discriminants and related estimates for class numbers, regulators and zeros of zeta functions: a survey of recent results

AM Odlyzko - Journal de théorie des nombres de …, 1990 - jtnb.centre-mersenne.org
Nous présentons une bibliographie d'articles récents sur les bornes inférieures des
discriminants de corps de nombres et sur des sujets voisins. Nous discutons quelques unes …

[SÁCH][B] Diophantine equations and power integral bases

I Gaál - 2002 - Springer
One of the classical problems in algebraic number theory, going back among others to
Dedekind [De78], Hensel [He08], and Hasse [Ha63], is to decide if an algebraic number field …

Solving solvable quintics

DS Dummit - mathematics of computation, 1991 - ams.org
Let $ f (x)={x^ 5}+ p {x^ 3}+ q {x^ 2}+ rx+ s $ be an irreducible polynomial of degree 5 with
rational coefficients. An explicit resolvent sextic is constructed which has a rational root if …

Connection between Gaussian periods and cyclic units

E Lehmer - Mathematics of Computation, 1988 - ams.org
This paper finds that all known parametric families of units in real quadratic, cubic, quartic
and sextic fields with prime conductor are linear combinations of Gaussian periods and …

Class numbers of real cyclotomic fields of prime conductor

R Schoof - Mathematics of computation, 2003 - ams.org
The class numbers $ h_ {l}^{+} $ of the real cyclotomic fields $\mathbf {Q}(\zeta _ {l}^{}+\zeta
_ {l}^{-1}) $ are notoriously hard to compute. Indeed, the number $ h_ {l}^{+} $ is not known …

Class groups and Selmer groups

EF Schaefer - journal of number theory, 1996 - Elsevier
It is often the case that a Selmer group of an abelian variety and a group related to an ideal
class group can both be naturally embedded into the same cohomology group. One hopes …

Simple families of Thue inequalities

G Lettl, A Pethő, P Voutier - Transactions of the American Mathematical …, 1999 - ams.org
We use the hypergeometric method to solve three families of Thue inequalities of degree 3,
4 and 6, respectively, each of which is parametrized by an integral parameter. We obtain …

Irregular primes to one million

JP Buhler, RE Crandall, RW Sompolski - mathematics of computation, 1992 - ams.org
Using" fast" algorithms for power series inversion (based on the fast Fourier transform and
multisectioning of power series), we have calculated all irregular primes up to one million …

Undecidability, unit groups, and some totally imaginary infinite extensions of ℚ

C Springer - Proceedings of the American Mathematical Society, 2020 - ams.org
We produce new examples of totally imaginary infinite extensions of $\mathbb {Q} $ which
have undecidable first-order theory by generalizing the methods used by Martínez-Ranero …

On the class number and unit index of simplest quartic fields

AJ Lazarus - Nagoya Mathematical Journal, 1991 - cambridge.org
The term “simplest” field has been used to describe certain totally real, cyclic number fields
of degrees 2, 3, 4, 5, 6, and 8. For each of these degrees, the fields are defined by a one …
