Hamiltonian Realization of spectra

C. B. Manzaneda, R. L. Soto

A $2 n \times 2 n$ real matrix $A$ is said to be a Hamiltonian matrix if $A^{T} J + J A = 0$ , where $J = (0 - I_{n} I_{n} 0)$ . Hamiltonian m…

Centrosymmetric nonnegative realization of spectra

Ana I. Julio, Oscar Rojo, Ricardo L. Soto

A list $Λ = {λ_{1}, λ_{2}, \dots, λ_{n}}$ of complex numbers is said to be realizable if it is the spectrum of an entrywise nonnegative matrix. In this paper we intent to characteri…
