The Classification and Geometric Interpretations of Hyperbolic Spinors Related to Split Quaternions
Abstract
This study investigates the relationship between split quaternions and hyperbolic spinors by considering the linear correspondence that assigns a hyperbolic spinor to each split quaternion. Based on this correspondence, hyperbolic spinors are classified by taking into account the algebraic classification of the associated split quaternions. In this way, different types of hyperbolic spinors are identified according to the character of the corresponding split quaternion. Using this relation, the hyperbolic spinor representations of the left and right multiplication matrices of split quaternions are explicitly constructed. We obtain these matrices and derive several identities describing their algebraic properties. Moreover, we show that the left hyperbolic spinor matrix plays a fundamental role within this structure. Its eigenvalues are computed and these values are classified according to the type of the corresponding hyperbolic spinors. The results provide a clear algebraic and geometric description of hyperbolic spinors arising from split quaternionic structures. This approach is expected to contribute to geometric algebra, differential geometry, algebra and relativistic physics where spinor representations are essential.
