Title:
Sub-critical behavior for quasi-periodic Jacobi operators

Speaker:
Chris Marx

Abstract:
In this talk we will present sufficient criteria implying sub-critical behavior for quasi-periodic Schrödinger- and, more generally, Jacobi operators if the sampling functions are trigonometric polynomials. For non-singular Jacobi operators, sub-critical behavior is known to imply purely absolutely continuous spectrum for Lebesgue almost every value of the phase.
