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.

Low Rank Pure Quaternion Approximation for Pure Quaternion Matrices [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2021
Quaternion matrices are employed successfully in many color image processing applications. In particular, a pure quaternion matrix can be used to represent red, green and blue channels of color images. A low-rank approximation for a pure quaternion matrix can be obtained by using the quaternion singular value decomposition.

Commutative Quaternion Matrices [PDF]

open access: yesAdvances in Applied Clifford Algebras, 2014
In this study, we introduce the concept of commutative quaternions and commutative quaternion matrices. Firstly, we give some properties of commutative quaternions and their Hamilton matrices. After that we investigate commutative quaternion matrices using properties of complex matrices.

Generalizing Frobenius inversion to quaternion matrices

open access: yesNumerical Algorithms, 2023
Abstract In this paper we derive and analyze an algorithm for inverting quaternion matrices. The algorithm is an analogue of the Frobenius algorithm for the complex matrix inversion. On the theory side, we prove that our algorithm is more efficient that other existing methods.
