Title:Monotonic quasiperiodic cocycles with singularities and application to the Maryland model

Abstract: We consider monotonic quasiperiodic SL(2, R) cocycles with singularities, and show that the Lyapunov exponent is analytic if the cocycle is meromorphic. This result implies that the Maryland model, which is a one-dimensional quasiperiodic Schrödinger operator, has analytic Lyapunov exponent.
