摘要:

本文引入四元数矩阵的二次数值域的定义,并且讨论了四元数矩阵二次数值域的一些性质?在一定条件下,证明了四元数矩阵的左特征值集合是该四元数矩阵二次数值值域的子集?这些结果有助于四元数矩阵左特征值及相关问题的研究?

关键词: 四元数矩阵')">">四元数矩阵, 左特征值')">">左特征值, 二次数值域')">">二次数值域, We present the definition of quadratic numerical range of a quaternion matrix, and discuss its properties. We further prove that the set of all left eigenvalues of such a matrix is its subset under certain restricted conditions. These results are benefit for the research on the left eigenvalues of a quaternion matrix and relative issues.
