Numerical Study of Convective Flow of Casson Fluid Through an Infinite Vertical Plate with Induced Magnetic Field

East European Journal of Physics
The present objective is to numerically analyze the induced magnetic field (IMF) effect of an unsteady MHD flow of Casson fluid through two infinite vertical plates. The effect of radiative heat has been scrutinized. Governing non-dimensional PDEs of the

Short Principal Ideal Problem in multicubic fields

Journal of Mathematical Cryptology, 2020
One family of candidates to build a post-quantum cryptosystem upon relies on euclidean lattices. In order to make such cryptosystems more efficient, one can consider special lattices with an additional algebraic structure such as ideal lattices.

The structure of the n-th roots of unity in residue rings of prime ideals P over p in algebraic number fields 177 [PDF]

Surveys in Mathematics and its Applications
Let 𝕂 be an algebraic number field and let O𝕂 be its ring of integers. In this paper, we study the structure of incongruent solutions of xn ≡ 1 (mod Pa) in O𝕂, where P is a prime ideal, in order to apply these results to solving xn = 1 over the P-adic ...

Algebraic leaves of algebraic foliations over number fields [PDF]

Publications Mathématiques de l'IHÉS, 2001
We prove an algebraicity criterion for leaves of algebraic foliations defined over number fields. Namely, consider a number field K embedded in C , a smooth ...

The algebraic moments of vorticity. Theory and numerical tests

Computer Assisted Methods in Engineering and Science, 2023
The paper presents the method of algebraic vorticity moments. It may be used to solve problems of viscous liquid motion in 2-D and 3-D cases. Its essence lies in the integration of a set of ordinary differentia equations.

Multilayer tube impedance and external radiation

Physical Review Special Topics. Accelerators and Beams, 2008
The paper describes a method for calculating the longitudinal and transverse impedances of the laminated round pipe with many layers of different materials. The charge is moving along the pipe axis with arbitrary constant velocity.

Discrete Cartesian Coordinate Transformations: Using Algebraic Extension Methods

Applied 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
