Artin L-Functions for Abelian Extensions of Imaginary Quadratic Fields [PDF]

, 2005
Let F be an abelian extension of an imaginary quadratic field K with Galois group G. We form the Galois-equivariant L-function of the motive h(Spec F)(j) where the Tate twists j are negative integers.

The number of standard forms of matrices over imaginary Euclidean quadratic rings with respect to the $(z,k)$–equivalence

Математичні Студії, 2022
The $(z,k)$--equivalence of matrices over imaginary Euclidean quadratic rings is investigated. The classes of matrices over these rings are selected for which the standard form with respect to $(z,k)$--equivalence is uniquely defined and equal to the ...

Topological Approach for Material Structure Analyses in Terms of R² Orientation Distribution Function

Mathematics, 2023
The application of solid mechanics theory for material behavior faces the discrete nature of modern or biological material. Despite the developed methods of homogenization, there are deviations between simulated and experiments results.

Quadratic forms in $I^n$ of dimension $2^n+2^{n-1}$

Comptes Rendus. Mathématique
For $n\ge 3$, confirming a weak version of a conjecture of Hoffmann, we show that every anisotropic quadratic form in $I^n$ of dimension $2^n+2^{n-1}$ splits over a finite extension of the base field of degree not divisible by $4$. The first new case is $

A Multidimensional Functional Equation Having Quadratic Forms as Solutions

Journal of Inequalities and Applications, 2007
We obtain the general solution and the stability of the m-variable quadratic functional equation f(x1+y1,…,xm+ym)+f(x1−y1,…,xm−ym)=2f(x1,…,xm)+2f(y1,…,ym).

Classifying Quadratic Forms Over Z2 in Three Variables

Journal of Mathematics, 2016
The quadratic forms in three variables over the field Z2 are classified. Some remarks are made about the group of equivalences GL(3,Z2) of the quadratic forms.

Toeplitz versus Hankel: semibounded operators [PDF]

Opuscula Mathematica, 2018
Our goal is to compare various results for Toeplitz \(T\) and Hankel \(H\) operators. We consider semibounded operators and find necessary and sufficient conditions for their quadratic forms to be closable. This property allows one to define \(T\) and \(

Signdefiniteness and Reduction to Full Squares for the Bundle of Tree Quadratic Forms

Известия Иркутского государственного университета: Серия "Математика", 2016
The paper discusses the investigation of the relation of signdefiniteness of the bundle of three quadratic forms with to the simultaneous diagonalization by congruenttransformation of matrices of the respective quadratic forms.
