DOI: 10.1016/j.laa.2021.10.016

Abstract: We study the real algebraic variety of real symmetric matrices with eigenvalue multiplicities determined by a partition. We present formulas for the dimension and Euclidean Distance Degree. We use representation theory to provide a rational… read more here.

DOI: 10.1155/2020/9240852

Abstract: This paper mainly investigates the verification of real eigenvalues of the real symmetric and persymmetric matrices. For a real symmetric or persymmetric matrix, we use eig code in Matlab to obtain its real eigenvalues on… read more here.
