Realizability of Two-dimensional Linear Groups over Rings of Integers of Algebraic Number Fields
Algebras and Representation Theory, 2009This paper is concerned with the following problem. Given the ring of integers \(O_K\) of an algebraic number field \(K\) and a positive integer \(n\), does there exist a finite subgroup \(G\) of \(\mathrm{GL}(n,O_K)\) such that \(O_KG=M(n,O_K)\), where \(O_KG\) is the \(O_K\)-span of \(G\)? In this case \(M(n,O_K)\) is a `Schur ring'.

A new method is described for computing an \(N=R^ m=2^{vm}\)-point complex discrete Fourier transform that uses quantization within a dense ring of algebraic integers in conjunction with a residue number system over this ring. The algebraic and analytic foundations for the technique are derived and discussed. The architecture for a radix-R fast Fourier

The ring of integers of an Abelian extension of an algebraic number field as a Galois module
Journal of Soviet Mathematics, 1982The ringO of integers of a finite Abelian extension K of an algebraic number field k is studied as a module over the group ring Λ=σ[G], where σ is the ring of integers of k and G is the Galois group of K/k. It is proved that the ring σ is a decomposable Λ-module if and only if there exists in K/k an intermediate extension K/F. F≠K, whose degree divides
