New results about the Inverse Eigenvalue Problem of a Graph

Roberto C. Díaz, Ana I. Julio

All graphs considered are simple and undirected. The Inverse Eigenvalue Problem of a Graph $G$ (IEP-G) aims to find all possible spectra for matrices whose $(i, j) -$ entry, for $i\ne…

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…
