Frequency dependence of Hölder continuity for quasiperiodic Schrödinger operators
Paul Munger
We prove estimates on the Hölder exponent of the density of states measure for discrete Schrödinger operators with potential of the form $V(n) = λ(\lfloor(n+1)β\rfloor - \lfloor nβ…

Orthogonal Polynomials on the Unit Circle with Fibonacci Verblunsky Coefficients, II. Applications
David Damanik, Paul Munger, William N. Yessen
We consider CMV matrices with Verblunsky coefficients determined in an appropriate way by the Fibonacci sequence and present two applications of the spectral theory of such matrice…
