Indices of diagonalizable and universal realizability of spectra

Charles R. Johnson, Ana I. Julio, Ricardo L. Soto

A list $Λ = {λ_{1}, \dots, λ_{n}}$ of complex numbers (repeats allowed) is said to be \textit{realizable} if it is the spectrum of an entrywise nonnegative matrix $A$ . $Λ$ is \text…

Row Cones, Perron Similarities, and Nonnegative Spectra

C. R. Johnson, Pietro Paparella

In further pursuit of the diagonalizable \emph{real nonnegative inverse eigenvalue problem} (RNIEP), we study the relationship between the \emph{row cone} $C_{r} (S)$ and th…
