摘 要: 四元数矩阵的特征值与奇异值在四元数矩阵理论的应用中起着重要作用。借助于分块矩阵及相关恒等式,给出了关于四元数矩阵特征值与奇异值的几个新的不等式,推广了实或复数域上矩阵特征值与奇异值不等式的相应结果,它们可望有助于推动四元数代数在量子力学、机器人技术等学科中的进一步应用。 The eigenvalue and the singular value of a quatemion matrix play important roles in the applications of quatemion matrix theory. By virtue of the blocked matrix and the corresponding identifies, several inequalities on the eigenvalue and the singular value of quatemion matrices are established, which generalize the corresponding results existing in the real or the complex matrix theory. results of this paper may help to improve the applications of quatemion algebra in such related fields as quantum mechanics, robot technology and the llke.
