Almost Periodic Szegö Cocycles with Uniformly Positive Lyapunov Exponents
David Damanik and Helge Krüger
We exhibit examples of almost periodic Verblunsky coefficients for
which Herman's subharmonicity argument applies and yields that the
associated Lyapunov exponents are uniformly bounded away from
zero.
