Commutation Methods for Schroedinger Operators with Strongly Singular Potentials
Aleksey Kostenko, Alexander Sakhnovich, Gerald Teschl
We explore the connections between singular Weyl-Titchmarsh theory and the single and double commutation methods. In particular, we compute the singular Weyl function of the commut…

The similarity problem for indefinite Sturm-Liouville operators with periodic coefficients
Aleksey Kostenko
We investigate the problem of similarity to a self-adjoint operator for -positive Sturm-Liouville operators with -periodic coefficients $q…
