Abstract: In this talk, we consider the one-dimensional discrete Schrodinger operators with potentials generated by the doubling map
on the unit circle. We show that if the potentials is monotonic, then the associated Lyapunov exponent is uniformly bounded away from zero for
all energies. This provides a second example of this kind after the trigonometric polynomials.
