NONLINEAR NYBERG CONSTRUCTION TRANSFORMS OVER ISOMORPHIC REPRESENTATIONS OF FIELDS GALOIS

open access: yesСистемный анализ и прикладная информатика, 2017
Further development of cryptographic algorithms based on the principles of many-valued logic requires more accurate research of non-binary cryptographic primitives – S-boxes.

Abelian number fields with frobenian conditions

open access: yesMathematika, Volume 72, Issue 4, October 2026.
Abstract We study the distribution of abelian number fields with frobenian conditions imposed on the conductor. In particular, we find an asymptotic for the number of abelian field extensions of a number field k$k$ whose conductor is the sum of two squares. We also discuss an application of the Brauer group of stacks to quadratic number fields.

Discrete Cartesian Coordinate Transformations: Using Algebraic Extension Methods

open access: yesApplied Sciences
It is shown that it is reasonable to use Galois fields, including those obtained by algebraic extensions, to describe the position of a point in a discrete Cartesian coordinate system in many cases. This approach is applicable to any problem in which the

On the Existential Theory of the Completions of a Global Field

open access: yesMathematische Nachrichten, Volume 299, Issue 9, Page 2680-2692, September 2026.
ABSTRACT We discuss the common existential theory of all or almost all completions of a global function field.

Quadratic subfields on quartic extensions of local fields

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
We show that any quartic extension of a local field of odd residue characteristic must contain an intermediate field. A consequence of this is that local fields of odd residue characteristic do not have extensions with Galois group A4 or S4 ...

THE DEVELOPMENT OF ALGORITHMS FOR CALCULATING THEORETICAL- NUMERICAL SIGNAL TRANSFORMATIONS WITH THE LEAST NUMBER OF MULTIPLICATIONS

open access: yesСовременная наука и инновации, 2022
When using a discrete Fourier transform (DFT) to solve digital signal processing (DSP) problems, errors occur in rounding or truncating the results of operations to the word length used by specialized processors (SP).

Modular analogs of character formulas and minimal lifts of modular forms

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.
Abstract If f$f$ is a mod‐3 eigenform of weight 2 and level Γ0(ℓ2)$\Gamma _0(\ell ^2)$ for a prime ℓ$\ell$ such that ℓ≡−1(mod3)$\ell \equiv -1 \pmod {3}$, and ℓ$\ell$ is a vexing prime for f$f$, we show that there is no obstruction to finding a minimal lift of f$f$, but that there is an obstruction to finding a nonminimal lift.

Computation of Hilbert sequence for composite quadratic extensions using different type of primes in Q

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
First, we will give all necessary definitions and theorems. Then the definition of a Hilbert sequence by using a Galois group is introduced. Then by using the Hilbert sequence, we will build tower fields for extension K/k, where K=k(d1,d2) and k=Q for ...

Quantum Information: A Brief Overview and Some Mathematical Aspects

open access: yesMathematics, 2018
The aim of the present paper is twofold. First, to give the main ideas behind quantum computing and quantum information, a field based on quantum-mechanical phenomena. Therefore, a short review is devoted to (i) quantum bits or qubits (and more generally
