Quaternion CR-submanifolds of a quaternion Kaehler manifold [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We study the quaternion CR-submanifolds of a quaternion Kaehler manifold. More specifically we study the properties of the canonical structures and the geometry of the canonical foliations by using the Bott connection and the index of a quaternion CR ...

Quaternion Backpropagation [PDF]

open access: yesCoRR, 2022
Quaternion valued neural networks experienced rising popularity and interest from researchers in the last years, whereby the derivatives with respect to quaternions needed for optimization are calculated as the sum of the partial derivatives with respect

One-dimensional quaternion Laplace transform: Properties and its application to quaternion-valued differential equations

open access: yesPartial Differential Equations in Applied Mathematics, 2023
This paper is devoted to the study of the quaternion Laplace transform, which is a natural generalization of the classical Laplace transform using the quaternion algebra. We find that some of its properties such as derivative, convolution and correlation

Hyers-Ulam stability of linear quaternion-valued differential equations [PDF]

open access: yesElectronic Journal of Differential Equations, 2023
In this article, we study the Hyers-Ulam stability of the first-order linear quaternion-valued differential equations. We transfer a linear quaternion-valued differential equation into a real differential system. The Hyers-Ulam stability results for the

Rotacija z enotskim kvaternionom ( = Rotation with unit quaternion) [PDF]

open access: yesGeodetski Vestnik, 2014
A quaternion is a hyper-complex number. A rule for quaternion multiplications allows us to use it as a rotation in three-dimensional space. The aim of this article is to present quaternion rotations to the Slovene professional geodetic public ...

Endotrivial modules over groups with quaternion or semi-dihedral Sylow 2-subgroup. [PDF]

open access: yes, 2013
Let G be a finite group with a Sylow 2-subgroup P which is either quaternion or semi-dihedral. Let k be an algebraically closed field of characteristic 2.

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
