Decay estimates for four dimensional Schrödinger, Klein-Gordon and wave equations with obstructions at zero energy
William R. Green, Ebru Toprak
We investigate dispersive estimates for the Schrödinger operator with is a real-valued decaying potential when there are zero energy resonances and eigenvalues in four…

The boundedness of wave operators for Schrödinger Operators with threshold singularities
Michael Goldberg, William R. Green
Let be a Schrödinger operator on with real-valued potential for and let . If decays sufficiently, the wave operators $W_{\pm}=s-…
