酉等价于复对称矩阵的几何判据

Unitary equivalence to a complex symmetric matrix: geometric criteria

Stephan Ramon Garcia, Levon Balayan

摘要:

本文根据矩阵与其伴随矩阵的特征空间之间的几何关系,给出了判定一个具有不同特征值的方阵是否酉等价于一个复对称矩阵的几种方法。等价地,我们刻画了复对称矩阵的酉轨道上具有不同特征值的矩阵。

英文摘要:

We develop several methods, based on the geometric relationship between the eigenspaces of a matrix and its adjoint, for determining whether a square matrix having distinct eigenvalues is unitarily equivalent to a complex symmetric matrix. Equivalently, we characterize those matrices having distinct eigenvalues which lie in the unitary orbit of the complex symmetric matrices.
