On the Spectra and Pseudospectra of a Class of Non-Self-Adjoint Random Matrices and Operators
Simon N. Chandler-Wilde, Ratchanikorn Chonchaiya, Marko Lindner
In this paper we develop and apply methods for the spectral analysis of non-self-adjoint tridiagonal infinite and finite random matrices, and for the spectral analysis of analogous…
