# Shooting function for 1D Schrödinger operators

@article{MacKay2022ShootingFF, title={Shooting function for 1D Schr{\"o}dinger operators}, author={R. S. MacKay}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2022}, volume={55} }

For Schrödinger operators with suitable 1D potentials, focussing particularly on those that go to infinity at infinity, a characteristic function is constructed, via shooting functions. It is proved to be entire and its zeroes to be the eigenvalues.

Oscillation theory locates the spectrum of a differential equation by counting the zeros of its solutions. We present a version of this theory for canonical systems $Ju'=-zHu$ and then use it to…
