There have been several recent proofs of one-dimensional Anderson localization based on positive Lyapunov exponent that hold for bounded potentials. We provide a Lyapunov exponent based proof for unbounded potentials, simultaneously treating the singular and unbounded Jacobi case by extending the techniques in a recent work by Jitomirskaya and Zhu.
