Almost Periodic Schrödinger Operators Along Interval Exchange Transformations

Schrodinger operator | interval exchange transformation | singular continuous epectrum.
Schrodinger operators with potentials along shift embedding of irreducible interval exchange transformations in a dense set, have pure singular continuous spectrum for Lebesgue almost all points of the interval. Such potentials are natural generalizations of the Sturnian case.
