# Computing Scattering Resonances

@article{BenArtzi2020ComputingSR, title={Computing Scattering Resonances}, author={Jonathan Ben-Artzi and Marco Marletta and Frank Rosler}, journal={arXiv: Spectral Theory}, year={2020} }

The question of whether it is possible to compute scattering resonances of Schrodinger operators - independently of the particular potential - is addressed. A positive answer is given, and it is shown that the only information required to be known a priori is the size of the support of the potential. The potential itself is merely required to be $\mathcal{C}^1$. The proof is constructive, providing a universal algorithm which only needs to access the values of the potential at any requested…
