Abstract
We consider positive pseudo-Hermitian matrices and study properties of their eigenvalues. Our results are analogous to classical results about the eigenvalues of Hermitian matrices: Cauchy interlacing property, Laplace transform of orbital measures, Horn’s convexity theorem. We consider also Horn’s problem in the setting of pseudo-Hermitian matrices.
To the memory of Takaaki Nomura.
