Decay of eigenfunctions of elliptic PDE's

Ira Herbst, Erik Skibsted

We study exponential decay of eigenfunctions of self-adjoint higher order elliptic operators on $R^{d}$ . We show that the possible critical decay rates are determined algebraically.…

Two-body threshold spectral analysis, the critical case

Erik Skibsted, Xue Ping Wang

We study in dimension $d \geq 2$ low-energy spectral and scattering asymptotics for two-body $d$ -dimensional Schrödinger operators with a radially symmetric potential falling off lik…
