Spectra, Pseudospectra, and Localization for Random Bidiagonal Matrices
Lloyd N. Trefethen, Marco Contedini, Mark Embree
There has been much recent interest, initiated by work of the physicists Hatano and Nelson, in the eigenvalues of certain random non-Hermitian periodic tridiagonal matrices and the…
