Potential scattering and the continuity of phase-shifts

Gell-Redman, Jesse; Hassell, Andrew


Let S(k) be the scattering matrix for a Schrödinger operator (Laplacian plus potential) on Rn with compactly supported smooth potential. It is well known that S(k) is unitary and that the spectrum of S(k) accumulates on the unit circle only at 1; moreove
