On the coexistence of absolutely continuous and singular continuous
components of the spectral measure for some Sturm-Liouville operators
with square summable potentials.

ABSTRACT. We prove that there exist some Sturm-Liouville operators with square
summable potentials such that the singular continuous component of the
spectral measure lies on the positive half-line.
