# De Branges functions of Schroedinger equations

@article{Baranov2015DeBF, title={De Branges functions of Schroedinger equations}, author={A. D. Baranov and Yurii Belov and Alexei Poltoratski}, journal={Collectanea Mathematica}, year={2015}, volume={68}, pages={251-263} }

We characterize the Hermite–Biehler (de Branges) functions E which correspond to Schroedinger operators with $$L^2$$L2 potential on the finite interval. From this characterization one can easily deduce a recent theorem by Horvath. We also obtain a result about location of resonances.
