Research Abstract

One of the most important problems in the scattering theory is the characterization of the scattering matrices. This investigation studies forward and inverse scattering problems for singular rank-one perturbations of a selfadjoint operator A. I obtain necessary and sufficient conditions for a function to be the phase shift of a singular rank-one perturbation of A. This result is closely related with the theory of point interactions.
