The converse of Weyl's eigenvalue inequality

Yi Wang, Sainan Zheng

We establish the converse of Weyl's eigenvalue inequality for additive Hermitian perturbations of a Hermitian matrix.

Inertia indices and eigenvalue inequalities for Hermitian matrices

Sai-Nan Zheng, Xi Chen, Lily Li Liu +1

We present a characterization of eigenvalue inequalities between two Hermitian matrices by means of inertia indices. As applications, we deal with some classical eigenvalue inequal…

Stieltjes moment sequences of polynomials

Huyile Liang, Jeffrey Remmel, Sainan Zheng

A sequence $(a_{n})_{n \geq 0}$ is Stieltjes moment sequence if it has the form $a_{n} = \int_{0}^{\infty} x^{n} d μ (x)$ for $μ$ is a nonnegative measure on $[0, \infty)$ . It is known that $(a…
