Periodic and Ergodic Spectral Problems

Co-author: Anton Gorodetski (UC Irvine)

In the study of ergodic Schrodinger operators, a central role is played by the Lyapunov exponent of the associated Schrodinger cocycle. We discuss a construction showing that the regime of zero Lyapunov exponents can contain pure point spectrum.
