“…First, the geometric properties of transformations using quaternionic and pseudo-quaternionic multiplications in 4-dimensional real vector space are given by Baharatti and Nagaraj, [3]. Later, some results were expressed by studying quaternionic curves in different spaces (eg Euclidean and Lorentzian spaces) by many mathematicians, [4,8,12]. As mentioned above, although the quaternionic curve and quaternionic Lorentzian curve has been studied by many mathematicians, this article is a different study with the quaternion terminology for a quaternionic Lorentzian curve.…”
