Asymptotics of the Weyl Function for Schrödinger Operators with Measure-Valued Potentials
Annemarie Luger, Gerald Teschl, and Tobias Wöhrer
We derive an asymptotic expansion for the Weyl function of a one-dimensional Schrödinger operator which generalizes the classical formula by Atkinson. Moreover, we show that the asymptotic formula can also be interpreted in the sense of distributions.
