Imbedded Singular Continuous Spectrum for Schrödinger Operators
A. Kiselev
We construct examples of potentials satisfying where the function is growing arbitrarily slowly, such that the corresponding Schröding…

Stability of Singular Spectral Types under Decaying Perturbations
A. Kiselev, Y. Last, B. Simon
We look at invariance of a.e. boundary condition spectral behavior under perturbations, , of half-line, continuum or discrete Schrödinger operators. We extend the results of del…
