Dispersion Estimates for Spherical Schrödinger Equations
Aleksey Kostenko, Gerald Teschl, and Julio H. Toloza
We derive a dispersion estimate for one-dimensional perturbed radial Schrödinger operators. 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.
