Eigenfunctions of positive integral Hankel operators
Alexander Pushnitski
We consider bounded positive semi-definite Hankel operators , realised as integral operators on the positive semi-axis. For each value of , not necessarily in the spectrum of…

Schrödinger operators on the half-line with integrable complex potentials
Alexander Pushnitski, František Štampach
In our previous work, we introduced the concept of a \emph{spectral pair} for a half-line Schrödinger operator with a \emph{complex} bounded potential , serving as a substitute…
