Solution of the Optimization Problem of Magnetotelluric Sounding in Quaternions by the Differential Evolution Method

open access: yesComputation
The article discusses the application of quaternion Fourier transforms and quaternion algebra to transform Maxwell’s equations. This makes it possible to present the problem of magnetotelluric sensing (MTS) in a more convenient form for research. Studies

Some properties of octonion and quaternion algebras

open access: yes, 2006
In 1988, J.R. Faulkner has given a procedure to construct an octonion algebra on a finite dimensional unitary alternative algebra of degree three over a field K. Here we use a similar procedure to get a quaternion algebra.

Dual Quaternion-Based Dynamic Modeling and Adaptive Neural Identification for Load-Assist Exoskeletons

open access: yesIEEE Access
This article addresses the challenge of modeling and controlling load-assist exoskeletons operating under dynamic and uncertain conditions. Traditional approaches often rely solely on dual quaternions for kinematic modeling, limiting their applicability ...

On some $p$-adic and mod $p$ representations of quaternion algebra over $\mathbb{Q}_p$

open access: yes, 2023
Let $D$ be the non-split quaternion algebra over $\mathbb{Q}_p$. We prove that a class of admissible unitary Banach space representations of $D^{\times}$ of global origin are topologically of finite length.Comment: 38 pages. Comments welcome

A Simultaneous Decomposition for a Quaternion Tensor Quaternity with Applications

open access: yesMathematics
Quaternion tensor decompositions have recently been the center of focus due to their wide potential applications in color data processing. In this paper, we establish a simultaneous decomposition for a quaternion tensor quaternity under Einstein product.

On a virtual work consistent three-dimensional Reissner–Simo beam formulation using the quaternion algebra

open access: yes, 2013
International audienceIn the paper, we present the Reissner–Simo beam theory in which the rotations are represented by quaternions. From the generalized virtual work principle, where the unity constraint of the rotational quaternion is properly ...

Quaternionic Bundles on Algebraic Spheres

open access: yesRocky Mountain Journal of Mathematics, 1996
It has remained an open question for many years whether there is a bijection between algebraic and topological vector bundles on spheres. If one denotes by \(\mathbb{F}\) one of the (skew) fields \(\mathbb{R}\), \(\mathbb{C}\) or \(\mathbb{H}\) and by \(A_n\) the coordinate ring \(\mathbb{R}[x_0,\dots,x_n]/(\sum x^2_1-1)\) of the sphere, then the more ...

Orders of quaternion algebras with involution

open access: yesJournal of Number Theory, 2018
We introduce the notion of maximal orders over quaternion algebras with orthogonal involution and give a classification over local fields, and a partial classification over algebraic number fields.
