摘　　要：研究了一类双曲分裂四元数表示矩阵的棣莫弗定理.首先,将对双曲分裂四元数的研究转化为对双曲分裂四元数表示矩阵的研究;其次,利用双曲分裂四元数的极表示,得到双曲分裂四元数表示矩阵的3种形式的棣莫弗定理,并对欧拉公式进行了推广;再次,得到双曲分裂四元数的表示矩阵方程的求根公式;最后,利用算例验证了所得结论的正确性.In this paper,de Moivre’s theorem for a matrix representation of a class of hyperbolic split quaternions is studied.Firstly,the study of hyperbolic split quaternions is transformed into the study of a matrix representation of hyperbolic split quaternions.Secondly,by using the polar representation of a hyperbolic split quaternion,the three forms of de Moivre’s theorem for a matrix representation of the hyperbolic split quaternion are obtained,and Euler’s formula is extended.Thirdly,the root-finding formula of the hyperbolic split quaternion matrix representation equation is obtained.Finally,the validity of the conclusions is verified with some examples.
