Title: On the Lipschitz continuity of spectral bands of Harper-like and
magnetic Schroedinger operators

Abstract: We show for a large class of discrete Harper-like and continuous
magnetic Schroedinger operators that their band edges are Lipschitz
continuous with respect to the intensity of the external constant
magnetic field.
