Bipowers in Number Fields [PDF]

open access: yesProceedings of the American Mathematical Society, 1985
The set of all solutions to the Fermat equation is given a structure. This structure is then characterized up to isomorphism in terms of certain subsets of the integers modulo a prime.

On the strongly ambiguous classes of some biquadratic number fields [PDF]

open access: yesMathematica Bohemica, 2016
We study the capitulation of $2$-ideal classes of an infinite family of imaginary bicyclic biquadratic number fields consisting of fields $\Bbbk=\Bbb Q(\sqrt{2pq}, {\rm i})$, where ${\rm i}=\sqrt{-1}$ and $p\equiv-q\equiv1 \pmod4$ are different primes ...

Generators and number fields for torsion points of a special elliptic curve [PDF]

open access: yesArab Journal of Mathematical Sciences, 2020
Let E be an elliptic curve with Weierstrass form y2=x3−px, where p is a prime number and let E[m] be its m-torsion subgroup. Let p1=(x1,y1) and p2=(x2,y2) be a basis for E[m], then we prove that ℚ(E[m])=ℚ(x1,x2,ξm,y1) in general.

Relative integral basis for algebraic number fields

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
At first conditions are given for existence of a relative integral basis for OK≅Okn−1⊕I with [K;k]=n. Then the constrtiction of the ideal I in OK≅Okn−1⊕I is given for proof of existence of a relative integral basis for OK4(m1,m2)/Ok(​m3).

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.

Quaternary quadratic lattices over number fields

open access: yes, 2018
We relate proper isometry classes of maximal lattices in a totally definite quaternary quadratic space (V,q) with trivial discriminant to certain equivalence classes of ideals in the quaternion algebra representing the Clifford invariant of (V,q).

Real quadratic number fields with metacyclic Hilbert $2$-class field tower [PDF]

open access: yesMathematica Bohemica, 2019
We begin by giving a criterion for a number field $K$ with 2-class group of rank 2 to have a metacyclic Hilbert 2-class field tower, and then we will determine all real quadratic number fields $\mathbb Q(\sqrt d)$ that have a metacyclic nonabelian ...

The number of solutions of cubic diagonal equations over finite fields

open access: yesAIMS Mathematics, 2023
Let $ p $ be a prime, $ k $ be a positive integer, $ q = p^k $, and $ \mathbb{F}_q $ be the finite field with $ q $ elements. Let $ \mathbb{F}_q^* $ be the multiplicative group of $ \mathbb{F}_{q} $, that is $ \mathbb{F}_q^* = \mathbb{F}_{q}\setminus\{0\}

PAC fields over number fields [PDF]

open access: yesJournal de théorie des nombres de Bordeaux, 2008
We prove that if K is a number field and N is a Galois extension of ℚ which is not algebraically closed, then N is not PAC over K.

Generalized Reed-Solomon codes over number fields and exact gradient coding

open access: yesAIMS Mathematics
This paper describes generalized Reed-Solomon (GRS) codes over number fields that are invariant under certain permutations. We call these codes generalized quasi-cyclic (GQC) GRS codes.
