Dispersion Estimates for Spherical Schrödinger Equations with Critical Angular Momentum
arXiv:1611.05210 · doi:10.4171/186-1/14
Abstract
We derive a dispersion estimate for one-dimensional perturbed radial Schrödinger operators where the angular momentum takes the critical value $l=-\frac{1}{2}$. We also derive several new estimates for solutions of the underlying differential equation and investigate the behavior of the Jost function near the edge of the continuous spectrum.
