Covariant Decomposition of the Three-Dimensional Rotations
Lecture Notes in Computer Science, 2014
The main purpose of this paper is to provide an alternative representation for the generalized Euler decomposition (with respect to arbitrary axes) obtained in [2,3] by means of vector parameterization of the Lie group SO(3). The scalar (angular) parameters of the decomposition are explicitly written here as functions depending only on the contravariant components of the compound vector-parameter in the basis, determined by the three axes. We also consider the case of coplanar axes, in which the basis needs to be completed by a third vector and in particular, two-axes decompositions.
Some new results on three-dimensional rotations and pseudo-rotations
2013
We use a vector parameter technique to obtain the generalized Euler decompositions with respect to arbitrarily chosen axes for the three-dimensional special orthogonal group SO(3) and the three-dimensional Lorentz group SO(2, 1). Our approach, based on projecting a quaternion (respectively split quaternion) from the corresponding spin cover, has proven quite effective in various problems of geometry and physics [1, 2, 3]. In particular, we obtain explicit (generally double-valued) expressions for the three parameters in the decomposition and discuss separately the degenerate and divergent solutions, as well as decompositions with respect to two axes. There are some straightforward applications of this method in special relativity and quantum mechanics which are discussed elsewhere (see [4]).

Generating Matrices of Rotations in Minkowski Spaces using the Lie Derivative
Scientific Journal for the Faculty of Science-Sirte University
This paper aims to generate materices of rotations in Minkowski using the Lie Derivative. The calculus on manifolds in Lorentzian spaces are used to generate matrices of rotation in three-dimensional Lorentz-Minkowski space which includes one axis in timelike and the other two are spacelike axes. The findings showed that the manifolds and their calculus dramatically increased the use of Lie derivative in many branches of mathematics and physics, The findings also revealed that matrices ( of rotation) leave one line ( axis) fixed and these matrices of rotation are used widely in differential geometry in physics. Furthermore, the findings demonstrated that any surfaces of revolution inside this space must be invariant under one of these matrices. The main result of this paper is a new procedure of creating rotational matrices explicitly using the Lie derivative and deriving it into a linear system of ordinary differential equaion. Solving this system leads to matrices of rotation that...
The relationship between the spin transformations of the special linear group of order 2, SL (2, C) and the aggregate SO(3) of the three-dimensional pure rotations when considered as a group in itself (and not as a subgroup of the Lorentz group), is investigated. It is shown, by the spinor map CT AXA X → which is an action of SL(2.C) on the space of Hermitian matrices, that the one-parameter subgroup of rotations generated are precisely those of angles which are multiples of. 2π
Complex Lorentz rotations on vectors⊕pseudovectors
Advances in Applied Clifford Algebras, 2001
We study the complex structure of the space of vectors and pseudovectors A_ ~ AI@A3 arising from the properties of the Hodge duality in 4-dimensionM spacetimes. This structure appears naturally in the framework of its real Clifford geometric algebra Ceu3 or C~3,1, in which the Hodge duality is the simple multiplication by the volume unit ~. Interpreting the linear combination of a scalar anda pseudoscalar c~ + ~~ asa complex number (A0@A4-~ C), the odd subspace A_ E C~ is a left/right complex linear space, previously studied by Sobczyk. From the real metric defining C_~, A_ inherits a natural complex bilinear norm N(a). Corresponding to this norm there is the group of complex Lorentz rotations Spinl,3(C), for which we find a formulation using exclusively the real algebra ~. We discuss its behaviour in some examples and find expressions for different decompositions into real and selfdual, real and anti-selfdual, and real and pure imaginary angle rotations. We finally apply our results to the implementation of the rotations corresponding to Euclidean and null signatures inside the real Lorentzian Clifford algebra C 91
About Parametric Representations of SO(n) Matrices and Plane Rotations
2012
Since a long time the group SO(n) is of a great interest in physics (space relativity theory, quantum electrodynamics, theory of elementary particles) and mechanics because of its numerous applications to problems of monitoring of unknown nonlinear systems. The present paper treats the basic theory of this group and it is shown that any transformation of the group SO(n) may be presented as a product of plane transformations in clear analytical forms, appropriate for practical applications. The approach presented here is inspired by the close analogy of plane rotations with the vector-parameterization of the SO(3) group.
On the Decomposition of the Infinitesimal (Pseudo-)Rotations
Relying on previously derived set of explicit solutions for the generalized Euler decomposition with respect to three arbitrary axes here we obtain the corresponding expressions in the case of infinitesimal (pseudo-)rotations. Possible generalizations, e.g., to higher dimensional groups and physical applications are briefly discussed as well.
Two-Component Spinorial Formalism Using Quaternions for Six-Dimensional Spacetimes
Advances in Applied Clifford Algebras, 2021
In this article we construct and discuss several aspects of the two-component spinorial formalism for six-dimensional spacetimes, in which chiral spinors are represented by objects with two quaternionic components and the spin group is identified with SL(2; H), which is a double covering for the Lorentz group in six dimensions. We present the fundamental representations of this group and show how vectors, bivectors, and 3-vectors are represented in such spinorial formalism. We also complexify the spacetime, so that other signatures can be tackled. We argue that, in general, objects built from the tensor products of the fundamental representations of SL(2; H) do not carry a representation of the group, due to the non-commutativity of the quaternions. The Lie algebra of the spin group is obtained and its connection with the Lie algebra of SO(5, 1) is presented, providing a physical interpretation for the elements of SL(2; H). Finally, we present a bridge between this quaternionic spinorial formalism for six-dimensional spacetimes and the four-component spinorial formalism over the complex field that comes from the fact that the spin group in six-dimensional Euclidean spaces is given by SU (4).
A Note on the Representation of Cosserat Rotation
Continuous Media with Microstructure, 2010
This brief article provides an independent derivation of a formula given by Kafadar and Eringen (1971) connecting two distinct Cosserat spins. The first of these, the logarithmic spin represents the time rate of change of the vector defining finite Cosserat rotation, whereas the second, the instantaneous spin, gives the local angular velocity representing the infinitesimal generator of that rotation. While the formula of Kadafar and Eringen has since been identified by Iserles et al. (2000) as the differential of the Lie-group exponential, the present work provides an independent derivation based on quaternions. As such, it serves to bring together certain scattered results on quaternionic algebra, which is currently employed as a computational tool for representing rigid-body rotation in various branches of physics, structural and robotic dynamics, and computer graphics.
