Effects of Inclined Magnetic Field and Porous Medium on Peristaltic Flow of a Bingham Fluid with Heat Transfer [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2021
The current paper aims to explain the peristaltic mechanism of a Bingham fluid with varying viscosity. The fluid is considered to flow within a porous medium and subjected to a magnetic field with significant inclination.

Root lattices in number fields

open access: yesBulletin of Mathematical Sciences, 2021
We explore whether a root lattice may be similar to the lattice 𝒪 of integers of a number field K endowed with the inner product (x,y) := TraceK/ℚ(x ⋅ 𝜃(y)), where 𝜃 is an involution of K.

On Hilbert class field tower for some quartic number fields [PDF]

open access: yesArab Journal of Mathematical Sciences, 2021
We determine the Hilbert 2-class field tower for some quartic number fields k whose 2-class group Ck,2 is isomorphic to ℤ/2ℤ×ℤ/2ℤ.

The Zeldovich Number: A Universal Dimensionless Measure for the Electromagnetic Field

open access: yesPhysics, 2023
In this paper we extend the Zeldovich formula, which was originally derived for the free electromagnetic field and was interpreted as the number of photons. We show that our extended formula gives a universal dimensionless measure of the overall strength

ε-arithmetics for real vectors and linear processing of real vector-valued signals

open access: yesJournal of Information and Intelligence, 2023
In this paper, we introduce a new concept, namely ε-arithmetics, for real vectors of any fixed dimension. The basic idea is to use vectors of rational values (called rational vectors) to approximate vectors of real values of the same dimension within ε ...

Topological Transcendental Fields

open access: yesAxioms, 2022
This article initiates the study of topological transcendental fields F which are subfields of the topological field C of all complex numbers such that F only consists of rational numbers and a nonempty set of transcendental numbers. F, with the topology
