Symmetries of the Feinberg-Zee Random Hopping Matrix
Raffael Hagger
We study the symmetries of the spectrum of the Feinberg-Zee Random Hopping Matrix. Chandler-Wilde and Davies proved that the spectrum of the Feinberg-Zee Random Hopping Matrix is i…

The Eigenvalues of Tridiagonal Sign Matrices are Dense in the Spectra of Periodic Tridiagonal Sign Operators
Raffael Hagger
Chandler-Wilde, Chonchaiya and Lindner conjectured that the set of eigenvalues of finite tridiagonal sign matrices ( on the first sub- and superdiagonal, everywhere else…

On the Spectrum and Numerical Range of Tridiagonal Random Operators
Raffael Hagger
In this paper we derive an explicit formula for the numerical range of (non-self-adjoint) tridiagonal random operators. As a corollary we obtain that the numerical range of such an…
