The Hecke Group Hλ4 Acting on Imaginary Quadratic Number Fields
Let Hλ4 be the Hecke group x,y:x2=y4=1 and, for a square-free positive integer n, consider the subset ℚ∗−n=a+−n/c|a,b=a2+n/c∈ℤ, c∈2ℤ of the quadratic imaginary number field ℚ−n.

Parallel machine arithmetic for recurrent number systems in non-quadratic fields [PDF]
The paper proposes a new method of synthesis of computer arithmetic systems for "error-free" parallel calculations. The difference between the proposed approach and calculations in traditional systems of Residue Number Systems for the direct sum of ...

BETTI NUMBERS OF GAUSSIAN FIELDS [PDF]
We present the relation between the genus in cosmology and the Betti numbers for excursion sets of three- and two-dimensional smooth Gaussian random fields, and numerically investigate the Betti numbers as a function of threshold level. Betti numbers are topological invariants of figures that can be used to distinguish topological spaces.

Computation of the Euclidean minimum of algebraic number fields [PDF]
30 pages, shorter version, with many typos fixedInternational audienceWe present an algorithm to compute the Euclidean minimum of an algebraic number field, which is a generalization of the algorithm restricted to the totally real case described by Cerri.

Relative integral basis for algebraic number fields
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).

ON WEIL NUMBERS IN CYCLOTOMIC FIELDS [PDF]
In this paper, we study the p-adic behavior of Weil numbers in the cyclotomic ℤp-extension of the pth cyclotomic field. We determine the characteristic ideal of the quotient of semi-local units by Weil numbers in terms of the characteristic ideals of some classical modules that appear in the Iwasawa theory.

On the Fontaine–Mazur Conjecture for Number Fields and an Analogue for Function Fields [PDF]
The Fontaine–Mazur Conjecture for number fields predicts that infinite ℓ-adic analytic groups cannot occur as the Galois groups of unramified ℓ-extensions of number fields.

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

A conductor formula for Abelian number fields
In this article, based on Kronecker-Weber theorem we explicitly give a conductor formula for the Abelian number fields in terms of the ramification indices. Particularly, the conductor of a quadratic number field can be easily deduced from this formula.

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