ABSTRACT
In this paper, we find the roots of lightlike quaternions. By introducing the concept of the Moore-Penrose inverse in split quaternions, we solve the linear equations axb = d, xa = bx, and axb = x. As applications, we obtain necessary and sufficient conditions for two split quaternions to be similar or pseudosimilar.

分裂四元数的摩尔-彭罗斯逆
摘要
在本文中,我们找到了类光四元数的根源。通过在分裂四元数中引入摩尔-彭罗斯逆的概念,我们求解线性方程axb = d,xa = bx,和axb = x。作为应用,我们获得了两个分裂四元数相似或伪相似的充要条件。
