  • On the spectrum and numerical range of tridiagonal random operators 
    Hagger, Raffael (Zürich : European Mathematical Society Publishing House, 2016)
    In this paper we derive an explicit formula for the numerical range of (non-selfadjoint) tridiagonal random operators. As a corollary we obtain that the numerical range of such an operator is always the convex hull of its ...
