Abstract
AbstractWe show that for any doubling map generated $$C^1$$

monotone potential with derivative uniformly bounded away from zero and infinity, the Lyapunov exponent of the associated Schrödinger operators is bounded below by $$\log {\lambda }-C$$

for all energies, where C depends only on the potential. In particular, it answers an open question [D, Problem 5] raised by D. Damanik.
