On perturbation bounds of eigenvalues in Euclidean Jordan Algebras
Kevin P. Seltzer, Jiyuan Tao · Linear and Multilinear Algebra · 2014
In matrix theory, C.-K. Li and R.-C. Li gave the best bound of the difference between eigenvalues of a real/complex Hermitian matrix and the matrix after removing off-diagonal blocks. In this paper, we extend this result to the setting of simple Euclidean Jordan Algebras.
