Multiscale Analysis for Ergodic Schrödinger operators and positivity of Lyapunov exponents

Helge Krueger

A variant of multiscale analysis for ergodic Schrödinger operators is developed. This enables us to prove positivity of Lyapunov exponents given initial scale estimates and an init…

A family of Schrödinger operators whose spectrum is an interval

Helge Krueger

By approximation, I show that the spectrum of the Schrödinger operator with potential for f continuous and , is an interval.
