The split and hyperbolic (countercomplex) octonions are eight-dimensional nonassociative algebras over the real numbers, which are in the form X = x(0)e(0) + Sigma(7)(j=1)x(j)e(j) e(m)'s (0 <= m <= 7) have different properties for them. the main purpose of this paper is to define the split-type octonion and its matrix whose inputs are split-type octonions and give some properties for them by using the real quaternions, split, and hyperbolic (countercomplex) octonions. on the other hand, to make some definitions, we present some operations on the split-type octonions. Also, we show that every split-type octonions can be represented by 2 x 2 real quaternion matrix and 4 x 4 complex number matrix. the information about the determinants of these matrix representations is also given. Besides, the main features of split-type octonion matrix concept are given by using properties of real quaternion matrices. Then, 8n x 8nreal matrix representations of split-type octonion matrices are shown, and some algebraic structures are examined. Additionally, we introduce real quaternion adjoint matrices of split-type octonion matrices. Moreover, necessary and sufficient conditions and definitions are given for split-type octonion matrices to be special split-type octonion matrices. We describe some special split-type octonion matrices. Finally, oct-determinant of split-type octonion matrices is defined. Definitive and understandable examples of all definitions, theorems, and conclusions were given for a better understanding of all these concepts.

A new approach on electromagnetism with dual number coefficient octonion algebra
Chanyal, Bhupesh Chandra; Chanyal, Sunil Kumar; Bektaş, Özcan; Yüce, Salim (World Scientific Publ Co Pte Ltd, 2016)Dual number coefficient octonion (DNCO) is one of the kind of octonion, it has 16 components with an additional dual unit epsilon. Starting with DNCO algebra, we develop the generalized electromagnetic field equations of ... -
Serret-frenet formulas for octonionic curves
Bektaş, Özcan; Yüce, Salim (Soc Paranaense Matematica, 2020)In this paper, we define spatial octonionic curves (SOC) in R( )(7)and octonionic curves (OC) in R-8 by using octonions. Firstly, we determine Serret-Frenet equations, and curvatures of the SOC in R-7. Then, Serret-Frenet ... -
Dual octonions and rigid body kinematics
Çakır, Hasan; Bektaş, Özcan; Yılmaz, Ruşen (Wiley, 2024)In this paper, we first give the basic information about octonions and present the Euclidean rotation matrix formed by an octonion in seven-dimensional Euclidean space. Next, we define and introduce the -module and dual ...
