Average value of the divisor class numbers of real cubic function fields

open access: yesOpen Mathematics, 2023
We compute an asymptotic formula for the divisor class numbers of real cubic function fields Km=k(m3){K}_{m}=k\left(\sqrt[3]{m}), where Fq{{\mathbb{F}}}_{q} is a finite field with qq elements, q≡1(mod3)q\equiv 1\hspace{0.3em}\left(\mathrm{mod}\hspace{0 ...

Stickelberger's congruences for absolute norms of relative discriminants [PDF]

open access: yes, 2010
We give an improvement of a result of J. Martinet on Stickelberger's congruences for the absolute norms of relative discriminants of number fields, by using classical arguments of class field ...

Some Questions on the Ideal Class Group of Imaginary Abelian Fields [PDF]

open access: yes, 2007
Let k be an imaginary quadratic field. Assume that the class number of k is exactly an odd prime number p, and p splits into two distinct primes in k. Then it is known that a prime ideal lying above p is not principal.

Capitulation of the 2-ideal classes of type (2, 2, 2) of some quartic cyclic number fields

open access: yesJournal of Mathematical Cryptology, 2019
Let p≡3(mod4){p\equiv 3\pmod{4}} and l≡5(mod8){l\equiv 5\pmod{8}} be different primes such that pl=1{\frac{p}{l}=1} and 2p=pl4{\frac{2}{p}=\frac{p}{l}_{4}}. Put k=ℚ⁢(l){k=\mathbb{Q}(\sqrt{l})}, and denote by ϵ its fundamental unit. Set K=k⁢(-2⁢p⁢ϵ⁢l){K=k(

Class number formulas via 2-isogenies of elliptic curves [PDF]

open access: yes, 2012
A classical result of Dirichlet shows that certain elementary character sums compute class numbers of quadratic imaginary number fields. We obtain analogous relations between class numbers and a weighted character sum associated to a 2-isogeny of ...

The average size of 3-torsion in class groups of 2-extensions

open access: yesForum of Mathematics, Pi
We determine the average size of the $3$ -torsion in class groups of G-extensions of a number field when G is any transitive $2$ -group containing a transposition, for example $D_4$ .

The minimum discriminant of number fields of degree 8 and signature (2,3)

open access: yes, 2018
In this paper we describe how to use the algorithmic methods provided by Hunter and Pohst in order to give a complete classification of number fields of degree 8 and signature (2,3) with absolute discriminant less than a certain bound. The choice of this
