Quaternion Electromagnetism and the Relation with Two-Spinor Formalism

open access: yesUniverse, 2019
By using complex quaternion, which is the system of quaternion representation extended to complex numbers, we show that the laws of electromagnetism can be expressed much more simply and concisely.

Field Equations in the Complex Quaternion Spaces [PDF]

open access: yesAdvances in Mathematical Physics, 2014
The paper aims to adopt the complex quaternion and octonion to formulate the field equations for electromagnetic and gravitational fields. Applying the octonionic representation enables one single definition to combine some physics contents of two fields,

Signal flow graph and control of realizable autonomous nonlinear Chen model with quaternion variables

open access: goldAlexandria Engineering Journal, 2020
In this work, we continue our study of autonomous nonlinear dynamical systems with quaternion variables. We present a novel chaotic Chen system with quaternion variables. This system in real form is high (nine) dimensional.

Consimilarity and quaternion matrix equations AX −^X B = C, X − A^X B = C

open access: yesSpecial Matrices, 2014
L. Huang [Consimilarity of quaternion matrices and complex matrices, Linear Algebra Appl. 331(2001) 21–30] gave a canonical form of a quaternion matrix with respect to consimilarity transformationsA ↦ ˜S−1AS in which S is a nonsingular quaternion matrix ...

The quaternion-type cyclic-Fibonacci sequences in groups [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
In this paper, we define the six different quaternion-type cyclic-Fibonacci sequences and present some properties, such as, the Cassini formula and generating function. Then, we study quaternion-type cyclic-Fibonacci sequences modulo m.

Some Essential Relations for the Quaternion Quadratic-Phase Fourier Transform

open access: yesMathematics, 2023
Motivated by the fact that the quaternion Fourier transform is a powerful tool in quaternion signal analysis, here, we study the quaternion quadratic-phase Fourier transform, which is a generalized version of the quaternion Fourier transform.

Characteristic of Quaternion Algebra Over Fields

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2023
Quaternion is an extension of the complex number system. Quaternion are discovered by formulating 4 points in 4-dimensional vector space using the cross product between two standard vectors. Quaternion algebra over a field is a 4-dimensional vector space

Dual quaternions and dual quaternionic curves [PDF]

open access: yesFilomat, 2019
After a brief review of the different types of quaternions, we develop a new perspective for dual quaternions with dividing two parts. Due to this new perspective, we will define the isotropic and nonisotropic dual quaternions. Then we will also give the basic algebraic concepts about the dual quaternions. Moreover, we define isotropic dual
