The diagonalizable nonnegative inverse eigenvalue problem
Anthony G Cronin, Thomas J Laffey
In this paper we prove that the SNIEP DNIEP, i.e. the symmetric and diagonalizable nonnegative inverse eigenvalue problems are different. We also show that the minimum …

Constructive methods for spectra with three nonzero elements in the nonnegative inverse eigenvalue problem
Anthony Cronin
We present and compare three constructive methods for realizing non-real spectra with three nonzero elements in the nonnegative inverse eigenvalue problem. We also provide some nec…
