Conditions for eigenvalue configurations of two real symmetric matrices (signature approach)
Hoon Hong, Daniel Profili, J. Rafael Sendra
For two real symmetric matrices, their eigenvalue configuration is the relative arrangement of their eigenvalues on the real line. We consider the following problem: given two para…

Conditions for eigenvalue configurations of two real symmetric matrices (symmetric polynomial approach)
Hoon Hong, Daniel Profili, J. Rafael Sendra
Given two real symmetric matrices, their eigenvalue configuration is the relative arrangement of their eigenvalues on the real line. In this paper, we consider the following proble…
