Time delay for the Dirac equation
Ivan Naumkin, Ricardo Weder
We consider time delay for the Dirac equation. A new method to calculate the asymptotics of the expectation values of the operator $\int\limits_{0} ^{\infty}e^{iH_{0}t}ζ\left( \fra…
Aharonov-Bohm Effect and High-Momenta Inverse Scattering for the Klein-Gordon Equation
Miguel Ballesteros, Ricardo Weder
We analyze spin-0 relativistic scattering of charged particles propagating in the exterior, , of a compact obstacle . The connected c…
High-Momenta Estimates for the Klein-Gordon Equation: Long-Range Magnetic Potentials and Time-Dependent Inverse Scattering
Miguel Ballesteros, Ricardo Weder
The study of obstacle scattering for the Klein-Gordon equation in the presence of long-range magnetic potentials is addressed. Previous results of the authors are extended to the l…
Scattering Theory for the matrix Schrödinger operator on the half line with general boundary conditions
Ricardo Weder
We study the stationary scattering theory for the matrix Schrödinger equation on the half line, with the most general boundary condition at the origin, and with integrable selfadjo…
