Split Semi-quaternions Algebra in Semi-Euclidean 4-Space

2014
Abstract.The aim of this paper is to study the split semi-quaternions,Hss;and to give some of their algebraic properties. We show that the set of unitsplit semi-quaternions is a subgroup ofHss:Furthermore, with the aid of DeMoivre's formula, any powers of these quaternions can be ...
