Split-Quaternions and the Dirac Equation [PDF]

open access: yesAdvances in Applied Clifford Algebras, 2014
We show that Dirac 4-spinors admit an entirely equivalent formulation in terms of 2-spinors defined over the split-quaternions. In this formalism, a Lorentz transformation is represented as a $2 \times 2$ unitary matrix over the split-quaternions. The corresponding Dirac equation is then derived in terms of these 2-spinors.

On the Consimilarity of Split Quaternions and Split Quaternion Matrices

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
In this paper, we introduce the concept of consimilarity of split quaternions and split quaternion matrices. In his regard, we examine the solvability conditions and general solutions of the equations and in split quaternions and split quaternion ...

Quaternionic Serret-Frenet Frames for Fuzzy Split Quaternion Numbers [PDF]

open access: yesAdvances in Fuzzy Systems, 2018
We build the concept of fuzzy split quaternion numbers of a natural extension of fuzzy real numbers in this study. Then, we give some differential geometric properties of this fuzzy quaternion.

The Second Order Pole over Split Quaternions

open access: yesJournal of Physics: Conference Series, 2014
This is an addition to a series of papers [FL1, FL2, FL3, FL4], where we develop quaternionic analysis from the point of view of representation theory of the conformal Lie group and its Lie algebra.

Split quaternion matrices [PDF]

open access: yesMiskolc Mathematical Notes, 2012
In this paper, we consider split quaternions and split quaternion matrices. Firstly, we give some properties of split quaternions. After that we investigate split quaternion matrices using properties of complex matrices. Then we define the complex adjoint matrix of split quaternion matrices and we describe some of their properties. Furthermore, we give

QUANTUM SPLIT QUATERNIONS

open access: yesJournal of Science and Arts, 2021
In this study we introduce q-deformed split quaternions, that is, this deformation reduces to classical split quaternions as q->1 where q is a real parameter. It is also shown that there is a quantum group associated with q-deformed split quaternions, which is isomorphic to SUq(1,1).

Quadratic Split Quaternion Polynomials: Factorization and Geometry. [PDF]

open access: yesAdv Appl Clifford Algebr, 2020
AbstractWe investigate factorizability of a quadratic split quaternion polynomial. In addition to inequality conditions for existence of such factorization, we provide lucid geometric interpretations in the projective space over the split quaternions.

Complex structures, T-duality and worldsheet instantons in Born sigma models

open access: yesJournal of High Energy Physics, 2022
We investigate doubled (generalized) complex structures in 2D-dimensional Born geometries where T-duality symmetry is manifestly realized. We show that Kähler, hyperkähler, bi-hermitian and bi-hypercomplex structures of spacetime are implemented in Born ...

Sextonians and the magic square [PDF]

open access: yes, 2004
Associated to any complex simple Lie algebra is a non-reductive complex Lie algebra which we call the intermediate Lie algebra. We propose that these algebras can be included in both the magic square and the magic triangle to give an additional row and ...
